To detect changes in the Quill editor's text, we can utilize the QuillController
, which provides a way to manage and interact with the editor's state.
Initialization: Create and initialize a
QuillController
instance. This controller is linked to the Quill editor and allows for the monitoring of text changes.late QuillController _quillController = QuillController.basic();
Listening to Text Changes: Add a listener to the
QuillController
to detect changes in the editor's content. This listener will trigger a callback function whenever the text within the editor changes.@override void initState() { super.initState(); _quillController.addListener(_onEditorTextChanged); }
Handling Text Changes: The callback function
_onEditorTextChanged
is invoked whenever the editor's content changes. Within this function, you can access the current text of the editor and perform any necessary logic.void _onEditorTextChanged() { final text = _quillController.document.toPlainText(); // Implement your logic here, such as searching for URLs or updating the UI. }
Cleanup: Remove the listener when the widget is disposed to prevent memory leaks or unintended behavior.
@override void dispose() { _quillController.removeListener(_onEditorTextChanged); super.dispose(); }
