text property
The current string the user is editing.
Implementation
String get text => value.text;
Setting this will notify all the listeners of this TextEditingController that they need to update (it calls notifyListeners). For this reason, this value should only be set between frames, e.g. in response to user actions, not during the build, layout, or paint phases.
This property can be set from a listener added to this TextEditingController; however, one should not also set selection in a separate statement. To change both the text and the selection change the controller's value. Setting this here will clear the current selection and composing range, so avoid using it directly unless that is the desired behavior.
Implementation
set text(String newText) {
value = value.copyWith(
text: newText,
selection: const TextSelection.collapsed(offset: -1),
composing: TextRange.empty,
);
}
