Improvements Add FletApp.wait_idle(idle_ms, timeout_ms): a host app can wait until an embedded app has rendered its UI and gone quiet - for example before taking a screenshot of it or reading its output after a restart. It returns idle, error (the app failed to start or crashed) or timeout, and costs nothing unless a call is pending (#6901) by @FeodorFitsner. Add TextField.on_paste_files: pasted f…
Improvements Update serious_python to 5.0.0. flet build now passes each exclude path and cleanup glob to it as a separate option, so paths containing commas are excluded correctly and brace globs such as **/{tests,docs} in a cleanup.app_files or cleanup.package_files list work (serious-python#253, #6890) by @FeodorFitsner. Add identifier to Semantics so native accessibility tools and widget tests…
Improvements Update python-build to 20260921 and serious_python to 4.7.1, bringing Pyodide 0.27.8, 0.29.5, and 314.0.7 for Python 3.12, 3.13, and 3.14, respectively. CPython versions and wheel platform tags are unchanged (python-build#42, serious-python#249) by @FeodorFitsner. Bug fixes Fix macOS crashes during native scientific imports and NumPy operations by increasing the embedded Python worker…
New features Client actions: an action property that performs gesture-gated work without a round trip to Python. Browsers only let a page open a file picker, write to the clipboard, show a share sheet or open a new tab while they are still handling the user's click or key press. Sending that click to your Python code and acting on the reply takes longer than the permission lasts, so on iOS Safari…
What's Changed fix(diff): reconcile value-equal child controls in prop fields of re-rendered components by @davidlawson in #6826 fix(web): surface a Pyodide startup failure instead of a blank page by @ndonkoHenri in #6827 fix(build): handle read-only files on Windows in rmtree to prevent PermissionError (fixes #6808) by @eminsk in #6817 feat: add flet-local-auth extension by @mccre110 in #6823 fix…
What's Changed Migrate flet.app to studio.flet.dev by @FeodorFitsner in #6749 fix: run auto-update after generator event handlers complete by @PythBuster in #6748 "Create new flet app" and "Declarative vs. Imperative" docs updated by @InesaFitsner in #6743 Fix ink effects and doubled padding on an animated inked Container by @FeodorFitsner in #6757 Don't bundle CanvasKit and Pyodide in CDN-mode we…
Bug fixes Fix every flet_ads control (BannerAd, InterstitialAd, NativeAd, ConsentManager) crashing on construction with RuntimeError: <Ad>(N) Control must be added to the page first, which made the package unusable since 0.85. The mobile-only platform guard read self.page from init(), which runs at construction — before the control is attached to the page — so the parent-chain lookup raised. The g…
Bug fixes Fix services registered after an embedded FletApp is opened never becoming usable on the host page — calling one failed with Timeout waiting for invoke method listener for <Service>(id).<method>. ServiceRegistry subclasses Service, so it registered itself on construction; when an embedded app's page built its own registry while the host page was still the current context, the embedded re…
Improvements An embedded FletApp can now run over the in-process dart_bridge transport instead of a socket. Set url="dartbridge://" and the client allocates a native channel, delivers its port through the new FletApp.on_connect event, and the host serves that port with a FletDartBridgeServer — so a Flet program hosted inside another Flet app (a gallery, a preview) exchanges messages at memcpy spee…
Bug fixes Fix code edits not taking effect under flet debug android: after re-running the command, the app kept executing the previously-unpacked, stale code instead of your changes. flet debug rebuilds and reinstalls the same-version APK on each iteration (flutter run does an update install that preserves app data), and serious_python's on-device extraction cache — keyed only on versionName+versi…
Improvements flet-mcp's get_api tool now covers top-level callables — the app entry point (run), reactive hooks (use_state, use_ref, use_effect, …), and decorators (component, memo, observable) — which previously returned not found because only classes were indexed. A new functions bucket in the API builder extracts each package's re-exported public callables and renders them with a signature: lin…
New features Add support for Python multiprocessing in packaged Flet desktop apps built with flet build macos, flet build windows, and flet build linux. multiprocessing APIs such as Process, ProcessPoolExecutor, the spawn/forkserver start methods, and the resource tracker now work in packaged desktop apps. Previously, worker processes re-executed sys.executable, which pointed to the app binary its…

What's Changed 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 t…
What's Changed feat(build): cache flet-build-template.zip; share FLET_CACHE_DIR with Gradle by @FeodorFitsner in #6558 feat(build): support custom entries in AndroidManifest via pyproject.toml by @FeodorFitsner in #6559 Full Changelog: v0.85.3.dev0...v0.85.3.dev1

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];…
What's Changed New features and improvements 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 segm…
What's Changed perf(flet-charts): faster MatplotlibChart rendering on native, simpler Python loop by @FeodorFitsner in #6479 fix: Duration fields decode to 0 when passed as float (#6478) by @FeodorFitsner in #6480 Full Changelog: v0.85.0.dev3...v0.85.0.dev4
