prefer-correct-static-icon-provider
Warns when a class with the @staticIconProvider annotation does not have IconData fields or any of those fields are not static.
All IconData fields must be static in order for tree shacking to work properly.
Example
❌ Bad:
abstract final class Some {
// LINT: IconData fields must be static const for the @staticIconProvider to have any effect.
// Try removing the annotation or making this field static const.
final IconData icon = IconData(1);
}
// LINT: This class has no IconData fields which makes @staticIconProvider redundant.
// Try removing the annotation or adding IconData fields.
abstract final class Some {}
✅ Good:
abstract final class Some {
static const IconData icon = IconData(1);
}
