Improvements

• Allow [tool.flet.android.permission] values to be TOML inline tables in addition to booleans — each key = "value" entry adds an android:<key>="<value>" attribute to the generated <uses-permission> element, unlocking modifiers like android:maxSdkVersion and android:usesPermissionFlags that real-world Android permissions (e.g. Bluetooth LE) require. The boolean form and the --android-permissions CLI flag are unchanged; a non-empty inline table is always emitted, an empty table ({}) is treated as false, and invalid value types fail the build with a clear error (#​6550, #​6551) by @​FeodorFitsner.
• Add [tool.flet.android.provider] for declaring custom <provider> entries in the generated AndroidManifest.xml. Each table key is the provider's android:name; entries become android:<key>="<value>" attributes on the generated element. A reserved meta_data sub-table emits nested <meta-data> children (scalar values render as android:value="…"; inline-table values render as android:<k>="<v>" so android:resource="@​xml/…" works). false / {} skip the entry; true and invalid value types fail the build with a clear error. The built-in androidx.core.content.FileProvider block is unchanged (#​6556, #​6559) by @​FeodorFitsner.
• Upgrade the bundled Pyodide runtime in the flet build web template from 0.27.5 to 0.27.7 (includes micropip 0.9.0) (#​6549) by @​FeodorFitsner.
• Drop generated web/canvaskit/ build artifacts (canvaskit.js/.wasm/.symbols and the chromium/ and skwasm/skwasm_st variants) from the flet build web template — these are produced by the Flutter web build and should not have been committed into the cookiecutter template (#​6549) by @​FeodorFitsner.
• Cache the downloaded flet-build-template.zip across builds. The build template is bound to an exact Flet version and is immutable, so on every flet build / flet debug after the first, the CLI now uses a previously-downloaded zip from $FLET_CACHE_DIR/build-template/v<flet-version>/ (defaulting to ~/.flet/cache/build-template/v<flet-version>/) instead of re-fetching it via cookiecutter. The CLI also exports FLET_CACHE_DIR into the child Gradle process, so serious_python_android >= 1.0.1 lands its Python dist tarballs (python-android-dart-<py>-<abi>.tar.gz) in the same cache root by default — fixing the multi-minute "Creating app shell" / downloadDistArchive_* delay on every Android debug build. Custom --template URLs and the local-dev template path are unchanged (#​6555, #​6558) by @​FeodorFitsner.
• Bump the bundled build template's serious_python dependency from 1.0.0 to 1.0.1 so Android builds pick up the new persistent Python-tarball cache + conditional-GET revalidation introduced in serious_python 1.0.1 (#​6558) by @​FeodorFitsner.

Bug fixes

• Fix flet.Router's default on_view_pop navigating to the wrong URL when an outlet=True layout sits between two views in manage_views=True mode. Popping such a view now targets the previous view entry's resolved URL — skipping outlet layouts and componentless grouping routes — instead of chain[-2], which could equal the current view's URL and strand the page route, making the next navigation to it a no-op (#​6533) by @​FeodorFitsner.
• Fix flet-audio.Audio.play()/seek() timing out when replaying after playback had completed: under the default ReleaseMode.RELEASE the source is freed on completion and is now re-prepared on replay (#​6536, #​6538) by @​ndonkoHenri.
• Fix ft.run(view=ft.AppView.FLET_APP_HIDDEN) briefly flashing the native window in the top-left corner during Windows desktop startup. The Windows runner now respects FLET_HIDE_WINDOW_ON_START and skips the first-frame Show() call so the window stays hidden until page.window.visible = True, matching the Linux desktop behavior; the same fix is applied to the flet build windows template runner so generated apps behave consistently. On Linux, pre-show window placement actions (page.window.center(), page.window.alignment) are now deferred until the window first becomes visible to avoid an analogous flash, and the window's focused state is preserved when a prevent_close handler cancels a close attempt (#​5897, #​5914, #​6527) by @​ihmily.

v0.85.2

New features

• Add Route(modal=True) to flet.Router for fullscreen-dialog modal overlays that don't replace the underlying view stack — closing the modal pops it without rebuilding the views underneath. Two flavours by placement: top-level modals are global (the base stack is rebuilt from the Router's last non-modal location), nested-child modals are local (the base stack is the chain above the modal in the route tree, so deep-link works from URL alone) (#​6516) by @​FeodorFitsner.
• Add Route(recursive=True) to flet.Router so a route can match itself as its own descendant — one View per consumed URL segment, ideal for tree-shaped URLs of unbounded depth (/folder/a/b/c produces a 4-View stack; back-swipe walks one segment at a time). Non-recursive children are tried before self-recursion at every depth, so a specific sibling (e.g. example/:gp*) wins over the recursive :slug without duplicating it at every level (#​6516) by @​FeodorFitsner.

Improvements

• flet.Router's default on_view_pop now navigates to the matched chain's parent (chain[-2].resolved_path) instead of views[-2].route, which is robust against apps that share a View.route value between sibling tab roots to suppress switch transitions. Apps that install their own page.on_view_pop before page.render_views() still take precedence. Each sub-chain (base + modal) renders with its own LocationInfo, so is_route_active(...) inside a base view sees the base URL while a global modal is open over it (#​6516) by @​FeodorFitsner.

Bug fixes

• Fix cross-tab session contamination on Flet web: opening the same app URL in a duplicated browser tab no longer steals the original tab's output connection via sessionStorage-cloned _flet_session_id. REGISTER_CLIENT now rejects session reuse when the existing session still has a live connection, allocating a fresh session for the second tab while preserving legitimate single-tab reconnect after refresh or network blip (where connection is already None) (#​6512, #​6513) by @​ihmily.

Bug fixes

• Fix TooltipTheme.decoration so it applies to controls using ft.Tooltip(...) when the tooltip does not explicitly set decoration or bgcolor (#​6432, #​6482) by @​ndonkoHenri.
• Fix flet-geolocator.Geolocator reliability on web and desktop: get_last_known_position() no longer crashes with TypeError: argument after ** must be a mapping, not NoneType and now returns Optional[GeolocatorPosition]; get_current_position() no longer hangs forever on web (Dart-side workaround for the upstream geolocator_web 4.1.3 inMicroseconds/inMilliseconds timeout typo) and uses sensible web defaults (time_limit: 30s, maximum_age: 5m); the previously-dropped configuration argument now actually reaches getCurrentPosition on the Dart side; the position stream is gated behind a registered on_position_change/on_error handler (with cancel-on-update to prevent leaks); and platform exceptions (LocationServiceDisabledException, PermissionDeniedException, PermissionDefinitionsNotFoundException, PermissionRequestInProgressException, PositionUpdateException, TimeoutException) are now translated into actionable error messages and surfaced to Python as RuntimeError without the default Exception: prefix (#​6487) by @​FeodorFitsner.
• Fix PEP 508 markers on flet's oauthlib/httpx deps not actually excluding those packages under Pyodide: the flet build web package platform has been renamed from Pyodide to Emscripten to match platform.system() inside the Pyodide runtime, and the markers now use platform_system != 'Emscripten', so the exclusion works both via flet build and a direct micropip.install("flet") in a Pyodide REPL. Requires serious_python >= 1.0.0, which is now pinned in the flet build template (#​6492) by @​FeodorFitsner.

New features

• Add configurable built-in, custom, hidden, and normal/fullscreen-specific controls to flet-video; Video.take_screenshot() for capturing video frames; and Video.on_position_change/Video.on_duration_change events (#​6463) by @​ndonkoHenri.
• Add declarative ft.Router component for @ft.component apps with nested routes, layout routes with outlets, dynamic segments, optional segments, splats, custom regex constraints, data loaders, active link detection, authentication patterns, and manage_views=True mode for view-stack navigation with swipe-back gestures and AppBar back button on mobile (#​6406) by @​FeodorFitsner.
• Add ft.use_dialog() hook for declarative dialog management from within @ft.component functions, with frozen-diff reactive updates and automatic open/close lifecycle (#​6335) by @​FeodorFitsner.

• Add scroll support to ResponsiveRow for responsive layouts whose content exceeds the available height (#​2590, #​6417) by @​ndonkoHenri.
• Add issues property to CodeEditor (along with Issue and IssueType types) for displaying code analysis error markers in the gutter, with analysis performed on the Python side (#​6407) by @​FeodorFitsner.
• Add Page.pop_views_until() to pop multiple views and return a result to the destination view (#​6326, #​6347) by @​brunobrown.
• Make NavigationDrawerDestination.label accept custom controls and add NavigationDrawerTheme.icon_theme (#​6379, #​6395) by @​ndonkoHenri.
• Add local_position and global_position to DragTargetEvent for target-relative and global pointer coordinates (#​6387, #​6401) by @​ndonkoHenri.
• Added PCM16 streaming to AudioRecorder, including on_stream chunks and direct upload support via AudioRecorderUploadSettings (#​5858, #​6423) by @​ndonkoHenri.
• Add Page.theme_animation_style for customizing the duration and curve of the theme cross-fade between theme and dark_theme (or disabling it with AnimationStyle.no_animation()), exposing Flutter's MaterialApp.themeAnimationStyle (#​6476) by @​FeodorFitsner.

Breaking changes

• Remove deprecated module-level margin, padding, border, and border_radius helper functions (all(), symmetric(), only(), horizontal(), vertical()) in favor of the corresponding Margin, Padding, Border, and BorderRadius classmethods (#​6425) by @​ndonkoHenri.

Deprecations

• Deprecate DragTargetEvent.x, DragTargetEvent.y, and DragTargetEvent.offset; use local_position for target-relative coordinates or global_position for global coordinates instead. These APIs are scheduled for removal in 0.88.0 (#​6387, #​6401) by @​ndonkoHenri.
• Deprecate Video.show_controls; set Video.controls to None to hide controls. This API is scheduled for removal in 0.88.0 (#​6463) by @​ndonkoHenri.
• Deprecate Video.playlist_add() and Video.playlist_remove(); mutate Video.playlist directly with list methods such as append() and pop(). These APIs are scheduled for removal in 0.88.0 (#​6463) by @​ndonkoHenri.

Bug fixes

• Fix control diffing for controls nested inside @value dataclass objects so they keep the nearest control parent/page context, and restore optional structured properties that are cleared to None and later set again (#​6463) by @​ndonkoHenri.
• Fix Page and View vertical centering when scrolling is enabled, including hidden scrollbars, so short content remains centered in the viewport (#​6446, #​6450) by @​ndonkoHenri.
• Reduce Linux memory retention when repeatedly removing flet_video.Video controls by linking media_kit video apps against mimalloc in run and build flows (#​6164, #​6416) by @​ndonkoHenri.
• Fix flet build and flet publish dependency parsing for project.dependencies and Poetry constraints with </<=, and add coverage for normalized requirement handling (#​6332, #​6340) by @​td3447.
• Fix CodeEditor background not filling the entire area when expand=True (#​6407) by @​FeodorFitsner.
• Handle unbounded width in ResponsiveRow with an explicit error, treat child controls with col=0 as hidden, and clarify Container expansion behavior when alignment is set (#​1951, #​3805, #​5209, #​6354) by @​ndonkoHenri.
• Fix find_platform_image selecting incompatible icon formats (e.g. .icns on Windows) by ranking glob results per target platform (#​6381) by @​HG-ha.
• Fix page.window.destroy() taking several seconds to close Windows desktop apps when prevent_close is enabled (#​5459, #​6428) by @​ndonkoHenri.
• Fix Page.show_drawer(), close_drawer(), and root/top view accessors (appbar, drawer, navigation_bar, controls, ...) failing with TypeError under Page.render_views() by unwrapping component-wrapped views and normalizing single-view returns (#​6413, #​6414) by @​FeodorFitsner.
• Fix auto_scroll on scrollable controls silently doing nothing unless scroll was also explicitly set (#​6397, #​6404) by @​ndonkoHenri.
• Fix Flet web returning index.html with a 200 OK for missing asset files; requests for paths with a file extension other than .html now return a proper 404, while route-like paths still fall back to index.html for SPA routing (#​6425) by @​ndonkoHenri.
• Fix Lottie failing to load local asset files on Windows desktop (and unreliably on other desktop platforms), so animations referenced by src="file.json" from the app's assets/ directory now display correctly (#​6386, #​6426) by @​ndonkoHenri.
• Fix Page.on_resize and Page.on_media_change not firing after mobile orientation changes (#​6457, #​6423) by @​ndonkoHenri.
• Fix flet pack desktop packaging so Windows and Linux bundles include the expected client archive, and Windows taskbar pins point to the packed app instead of the cached flet.exe (#​5151, #​6403) by @​ndonkoHenri.
• Fix environment variable priority in flet build template: inherit from Platform.environment and use putIfAbsent for FLET_* variables so pre-set system env vars are not overwritten (#​6394) by @​Bahtya.
• Fix NavigationBarDestination.selected_icon rendering wrongly when provided as an Icon control (#​6460, #​6468) by @​ndonkoHenri.
• Fix 3- and 4-digit hex color shorthand (e.g. #c00, #fc00) rendering as invisible by expanding them to their full 6/8-digit forms (#​6419, #​6421) by @​ndonkoHenri.
• Fix LineChartEvent.spots returning undecoded MessagePack extension values instead of LineChartEventSpot objects (#​6443, #​6468) by @​ndonkoHenri.
• Fix LineChart (and other charts) silently dropping custom ChartAxisLabel entries whose value matched a tick only after floating-point rounding (e.g. 0.1, 0.2, 0.3) by switching label lookup to a tolerance-based comparison scaled to the axis interval (#​6445, #​6459) by @​KangZhaoKui.
• Fix absolute-path src (e.g. Image(src="/images/foo.svg")) breaking on web when the app is mounted at a non-root URL, pass data:/blob: URIs through the asset resolver unchanged, preserve origin-relative semantics when assets_dir is unset, and add a window.flet.assetsDir JS-interop bridge so embedding hosts can supply assets_dir to the top-level FletApp (#​6470) by @​FeodorFitsner.
• Fix unbounded browser memory growth in MatplotlibChart on Flutter web (CanvasKit/WASM) during animations by replacing the Canvas + capture() rendering path with a dedicated MatplotlibChartCanvas widget that composites matplotlib diff frames in CPU memory; also fixes Safari async PNG decode (EncodingError: Loading error.), a render/figure.savefig() race that crashed the toolbar Download, and pan/zoom playback lag from buffered pointer events (#​6473) by @​FeodorFitsner.
• Fix Duration fields (and other int-typed properties) silently decoding to 0 when given a Python float (e.g. Duration(seconds=2.0) causing Page.theme_animation_style to end instantly) by coercing double to int in the Dart-side parseInt (#​6478, #​6480) by @​FeodorFitsner.
