flet 1.0.2

v1.0.2

on Python PyPI

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 can match a stable ID (Android resource-id, iOS accessibilityIdentifier, web flt-semantics-identifier) instead of visible labels, plus Tester.find_by_semantics_identifier() (#6832) by @mccre110.
• flet run and ft.run() now print a warning with the desktop client's path when they use one from a previous flet build in build/<platform>, so an outdated client that lacks an extension is easy to spot (#6821) by @ndonkoHenri.
• flet build and flet debug pass the arguments that follow a -- separator to Flutter, e.g. flet build apk -- --obfuscate --split-debug-info=build/symbols, as an alternative to repeating --flutter-build-args (#6879) by @ndonkoHenri.
• flet pack passes the arguments that follow a -- separator to PyInstaller, e.g. flet pack main.py -- --clean, as an alternative to repeating --pyinstaller-build-args (#6879) by @ndonkoHenri.
• flet test passes the arguments that follow a -- separator to pytest, e.g. flet test -k screenshot -- -x --maxfail=1 (#6879) by @ndonkoHenri.

Bug fixes

• Fix the Android SDK auto-installation failing on Windows (#6522, #6892) by @ndonkoHenri.

• Fix InteractiveViewer failing to render when alignment is set (#6744, #6887) by @ndonkoHenri.

• flet-charts: Fix ScatterChart failing to render when a ScatterChartSpot has x_error or y_error set. Error ranges are now set with the new ChartErrorRange type and drawn as error bars in the color of their spot (#6885) by @ndonkoHenri.

• Fix iOS apps that use sqlite3 stopping with Assertion failed: (0), function isBulkReadStatement when run from Xcode on iOS 18 and later, by turning off Xcode's Thread Performance Checker in the scheme generated by flet build (#5480, #6882) by @ndonkoHenri.

• Fix Button(icon=...) and other material buttons rendering an error box when content is not set. Icon-only buttons now render the icon centered (#6886, #6889) by @FeodorFitsner.

• Fix flet debug, flet build, flet test, flet emulators and flet run rejecting a positional argument typed after an option on Python 3.10, 3.11, 3.12.0-3.12.6 and 3.13.0 - flet debug ios --device-id X my_app failed with unrecognized arguments: my_app - by backporting the upstream argparse fix (CPython gh-59317). Also, an app path pointing to a file such as main.py is now rejected with a clear error instead of crashing on main.py/build, and a bad app path fails before the Flutter toolchain is set up (#6840, #6875) by @ndonkoHenri.

• Fix --android-extract-packages keeping only the values of its last occurrence when repeated. Like the other list options of flet build, repeating it now adds to the list (#6875) by @ndonkoHenri.

• Fix --flutter-build-args handing a value that starts with - to Flet instead of Flutter - --flutter-build-args --verbose turned on Flet's own verbose output - and overriding build_args from pyproject.toml with an empty list. Such an occurrence now fails with a hint to attach the value using =, e.g. --flutter-build-args=--obfuscate (#6879) by @ndonkoHenri.

• Fix --pyinstaller-build-args handing a value that starts with - to Flet instead of PyInstaller - --pyinstaller-build-args -y turned on Flet's own -y - or rejecting it as unrecognized. Such an occurrence now fails with a hint to attach the value using = or to pass it after -- (#6879) by @ndonkoHenri.

• Fix flet build packaging virtual environments, .git, .flet and other development files into the app. Hidden entries in the app root (a leading ., or the hidden attribute on Windows), virtual environments detected by pyvenv.cfg, and __pycache__ directories are now excluded by default, and the build prints what was excluded (#6839, #6890) by @FeodorFitsner.

  Compatibility: .env and other dot-prefixed files in the app root are no longer packaged. Keep them with --include .env or include = [".env"] under [tool.flet.app], or turn default exclusions off with --no-default-excludes / default_excludes = false. Apps built with earlier versions may already contain .venv or .flet.

• Fix an empty list or table under [tool.flet.<PLATFORM>] falling back to the global [tool.flet] value. app.exclude, source_packages, dev_packages, target_arch, extract_packages, cleanup.app_files, cleanup.package_files and flutter.build_args now treat [] or {} in a platform section as "none for this platform" (#6890) by @FeodorFitsner.

Other changes

• Simplify HTTP request handling in AuthorizationService and GitHubOAuthProvider using HTTPX client methods and built-in JSON parsing (#6870) by @osamalzabidi.
