## Flutter: expand TextField height to match parent widget

To expand the height of TextField to match the parents widgets height, the following code can be used:

Container(
height: 500.0,
child: TextField(
expands: true,
minLines: null,
maxLines: null,
...
),
),


The important thing is, that both minLines and maxLines need to be set to null.

To set the height of the Container to match it’s parent or even the complete screen, height can be set to double.infinity.
