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.
