// hand rolled replacement for shadcn's Select (dropdown + popover).
|
|
// pixel-identical port of shadcn_flutter 0.0.52 form/select.dart — the closed
|
|
// outline trigger, the popover surface (card bg, muted border, xl radius) and
|
|
// the ghost item buttons with their check trailing.
|
|
//
|
|
// we only build the slice the app actually uses: single-select, static item
|
|
// lists + the searchable builder popup. multi-select / controlled / theming
|
|
// variants aren't wired up here (nothing in the app touches them).
|
|
//
|
|
// like the other GarageUI files we still read shadcn's Theme/ColorScheme + the
|
|
// scaleAlpha extension + the bundled LucideIcons during the migration. that
|
|
// import gets repointed later. everything else is plain flutter.
