Flutter_form_builder: The non-abstract class 'ChipsInputState' is missing implementations v3.7.2 [Latest]

[rdcoder33]

I can't run my flutter app. I am not even using chips input in my forms.

flutter_form_builder: ^3.7.2

Error:

+1 same here... Issue is open on its own repo: https://github.com/danvick/flutter_chips_input/issues/27
Hot-patching by adding this to chips_input.dart will at least let you compile - warning, not tested at all.

@override
TextEditingValue get currentTextEditingValue => _value;

I am seeing the same problem. I've tried hot patch with no luck.

@sgalway00 It worked for me. However, note you have to patch chips_input.dart (not text_input.dart)

This issue is fixed in v3.7.3

It's still an issue with v3.8.2 and Flutter 1.18.0-5.0.pre.37:

Error: The non-abstract class 'ChipsInputState' is missing implementations for these members:
 - TextInputClient.showAutocorrectionPromptRect
Try to either
 - provide an implementation,
 - inherit an implementation from a superclass or mixin,
 - mark the class as abstract, or
 - provide a 'noSuchMethod' implementation.

class ChipsInputState<T> extends State<ChipsInput<T>>
      ^^^^^^^^^^^^^^^
/C:/Flutter/packages/flutter/lib/src/services/text_input.dart:764:8: Context: 'TextInputClient.showAutocorrectionPromptRect' is defined here.
  void showAutocorrectionPromptRect(int start, int end);
       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To fix this, add this as a dependency: flutter_chips_input: ^1.9.0-dev.1
