controllerattribute assigned to theTextEditingController. - Utilize the
InputDecorationproperty to add a suffix icon, specifically anIconButtonwith a clear icon. - Link the
onPressedevent of the IconButton to theclearmethod of the TextEditingController.
Code Example

onPressed: _controller.clear,
icon: Icon(Icons.clear),
