- Migrate to Flutter built-in Kotlin: set builtInKotlin=true and
newDsl=true in gradle.properties; remove id(kotlin-android) from
app/build.gradle.kts. Eliminates the Kotlin Gradle Plugin WARNING
that caused 8 stderr lines in the VS Code Debug console.
- Fix DashboardController lifecycle in MobileShell: move controller
creation from _buildBody() (called on every rebuild) to
didChangeDependencies() so it is initialised once and reused.
Prevents repeated data loads on every tab switch and resolves the
203 skipped frames Choreographer warning.
- Fix KcSummaryCard RenderFlex overflow (8 cards, 19px each): reduce
icon size 28->22px, switch spacing to xs, wrap value Text in
FittedBox(scaleDown) with fontSize 28, use bodySmall + maxLines for
label. Cards now fit within the GridView childAspectRatio:1.6
constraint on all phone screen sizes.
All tests pass: 27 kell_mobile + 41 design_system.
