selectPosition method Null safety
- {required SelectionChangedCause cause}
Move selection to the location of the last tap down.
This method is mainly used to translate user inputs in global positions into a TextSelection. When used in conjunction with a EditableText, the selection change is fed back into TextEditingController.selection.
If you have a TextEditingController, it's generally easier to
programmatically manipulate its value or selection directly.
Implementation
void selectPosition({ required SelectionChangedCause cause }) {
selectPositionAt(from: _lastTapDownPosition!, cause: cause);
}
