To-do list
- Ability to limit the number of chips
- Overlay doesn't move when input height changes i.e. when chips wrap
- Create a
FormField
implementation (ChipsInputField
) to be used within Flutter Form Widget
Known Issues
- Deleting chips with keyboard on IOS makes app to crush (Flutter Issue with special characters used as replacement characters). Already reported #1
- For some reason Overlay floats above AppBar when scrolling
