- Allow setting ExternalGestureHandling through the InputHandler constructor
Fixes
- Fixed control characters being included in TextInput
- Fixed TextInputs behaving incorrectly when switching between multiline and single-line modes
- Fixed TextInput drawing characters with the wrong width if a masking character is used
- Fixed a multiline TextInput's cursor not returning to the default position when the last character is removed
Improvements
- Increased TextFormatter macro recursion limit to 64
- Allow changing the default values used by default TextFormatter codes
- Allow setting ExternalGestureHandling through the InputHandler constructor
