Raise the declared minimums in pubspec.yaml to what our deps already
require: Flutter >=3.35.0 / Dart >=3.9.0 (was 3.19.0 / 3.5.0). alchemist
0.12 needs Flutter 3.32; Dart 3.9 first ships in Flutter 3.35, so 3.35 is
the binding floor. Pin the exact build toolchain in .fvmrc (Flutter
3.44.1).
Moving to the Dart 3.9 language level switches `dart format` to the new
"tall" style and enables two new lints. This commit is the resulting
mechanical churn, isolated from any behaviour change:
- whole-tree `dart format` reformat (tall style)
- `dart fix` for unnecessary_underscores + use_null_aware_elements
No runtime behaviour change; `make test` green.

Four widget tests in test/builtin/welcome/dialog_test.dart driving
the WelcomeView open-folder fallback dialog. Uses a custom harness
that wraps the standard widget harness in a DialogHost so the
kernel.dialog.show() call inside _openFolder actually renders.
- MissingPluginException on pickDirectory → _OpenProjectDialog
appears with the expected title / hint / Cancel / Open chrome.
- Cancel dismisses the modal cleanly.
- Open with an empty path is a no-op (early return in _submit).
- Open with a non-repo path keeps the dialog (project.open returns
false, _loading flag flips back).
Coverage clears the **90% T-91 target**: 89.93% -> 90.53%. Floor
bumped to 90.
