[pve-devel] [PATCH pve_flutter_frontend 0/4] fix: add fix for dart-analyze issues and replace deprecated APIs

[Shan Shaji]

After upgrading to Flutter v3.35, the dart analyze command reported 
several issues. This patch series resolves them by applying `dart fix`
to automatically correct issues where possible. For cases where 
automated fixes were not available, I manually replaced deprecated 
APIs and addressed linting errors.

Shan Shaji (4):
  fix: run `dart fix` to fix the problems identified by diagnostic
  cleanup: dart-analyze: add explicit type annotation
  fix: dart-analyze: remove deprecated props and use `RadioGroup`
  chore: add upper bound flutter constraint and update dart sdk
    constraint

[pve-devel] [PATCH pve_flutter_frontend 1/4] fix: run `dart fix` to fix the problems identified by diagnostic

[Shan Shaji]

After the update to v3.35, `dart analyze` has reported some "problems"
which were identfied by the diagnostic. Fixed problems which had
associated fixes by running `dart fix`.

[pve-devel] [PATCH pve_flutter_frontend 2/4] cleanup: dart-analyze: add explicit type annotation

[Shan Shaji]

The lint warns about every omitted return type, parameter type, and
variable type of a top-level declaration. Inorder to fix the issue add
explicit type annotation.

[Shan Shaji]

Starting from flutter v3.32 [0] the `groupValue` and `onChanged` has
been deprecated from `RadioListTile` and need to use `RadioGroup`
widget. Fixed the issue by wrapping the group of `RadioListTile`
widgets with `RadioGroup` [1].

[pve-devel] [PATCH pve_flutter_frontend 4/4] chore: add upper bound flutter constraint and update dart sdk constraint

[Shan Shaji]

Starting form language version 3.9, the flutter constrain upper bound is
now respected in the root package. Setting the flutter constraint can be
usefull to ensure everyone will use the same SDK.

not sure if we want to make it that hard of a requirement

maybe having

flutter: '>=3.35.0 <3.36.0'

would be better ?

then we don't have to update this on every minor patch version?
