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
