…rious_python 4.3.4) `flet debug android` kept running previously-unpacked, stale app code after a re-run. `flet debug` 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+versionCode` — never saw the version change, so it skipped re-unpacking the new `app.zip`. Bump the build template's serious_python pin to 4.3.4, which folds the APK's `lastUpdateTime` into the cache key so every (re)install re-extracts the current code. `flet build apk` was never affected. Fixes #6682

Summary
Fixes #6682 — code edits not taking effect under
flet debug android.flet debug androidre-packages the app, rebuilds the APK, andflutter run -d <device>reinstalls it, so the new code is in the freshly installed APK's assets. But on Android,serious_pythoncopies the app payload out of the APK to a writable dir only when its cache key changes, and that key wasversionName+versionCode.flet debugnever bumps the version between iterations, andflutter rundoes an update install that preserves app data (including the cache marker), so the key never changed → re-extraction was skipped → the app kept running stale code.flet build apkwas never affected (fresh/version-bumped install), which matched the reporter's observation. iOS/desktop are also unaffected — they run the app straight from the read-only app bundle, whichflutter runfully replaces each reinstall.Change
Bump the
flet buildtemplate'sserious_pythonpin 4.3.3 → 4.3.4. serious_python 4.3.4 folds the APK'sPackageManager.lastUpdateTimeinto the extraction cache key, so every (re)install re-extracts the current code while ordinary relaunches still hit the cache.Files, mirroring the 0.86.1 release-prep convention:
sdk/python/templates/build/.../pubspec.yaml— pin bump.CHANGELOG.md—## 0.86.2bug-fix entry.packages/flet/CHANGELOG.md+packages/flet/pubspec.yaml— Dart package version bumped for release coordination (no code change).This depends on serious_python 4.3.4, which is prepared in flet-dev/serious-python#235 but not yet published to pub.dev. Do not merge/release this until 4.3.4 is live on pub.dev, or
flet buildwill fail to resolve the pin.Verification
Not exercised on a device here. End-to-end check once 4.3.4 is published:
flet debug android→ confirm app shows → editmain.py→flet debug androidagain → confirm the edit now appears (previously it wouldn't).Summary by Sourcery
