Error: The non-abstract class 'ChipsInputState' is missing implementations for these members:

• TextInputClient.insertTextPlaceholder
• TextInputClient.removeTextPlaceholder
• TextInputClient.showToolbar

[davebound]

Cause is this breaking change in flutter sdk: https://docs.flutter.dev/release/breaking-changes/scribble-text-input-client

Fix would be to add these methods to class ChipsInputState in chips_input.dart:

 @override
  void showToolbar() {}

  @override
  void insertTextPlaceholder(Size size) {}

  @override
  void removeTextPlaceholder() {}
