v0.85.0

Compare Source

New features

• 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, deprecating x, y, and offset (#​6387, #​6401) by @​ndonkoHenri.

Improvements

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.

Documentation

• Improve CrocoDocs API reference rendering with formatted signatures, modern type annotations, and cleaner cross-reference labels for extension packages (#​6442) by @​ndonkoHenri.
• Add crocodocs watch command for hot-reload docs development with file-watching, debounced regeneration, and optional child process management (#​6402) by @​ndonkoHenri.

Other changes

• Add a declarative ReorderableListView app example showing add, remove, and reorder flows with stable item identity (#​6374) by @​FeodorFitsner.
• Remove deprecated module-level margin, padding, border, and border_radius helpers (all(), symmetric(), only(), horizontal(), vertical()) in favor of the corresponding Margin, Padding, Border, and BorderRadius classmethods (#​6425) by @​ndonkoHenri.
• Centralize Linux apt dependencies in flet.utils.linux_deps and update CI workflows and publish docs to consume them dynamically (#​6357, #​6383) by @​ndonkoHenri.
• Bump serious_python to 0.9.12 in the flet build template (#​6461) by @​FeodorFitsner.
