Question

How to customise TextField\'s width and height?

Answer 1

You can try the margin property in the Container. Wrap the TextField inside a Container and adjust the margin property.

new Container(
  margin: const EdgeInsets.only(right: 10, left: 10),
  child: new TextField( 
    decoration: new InputDecoration(
      hintText: 'username',
      icon: new Icon(Icons.person)),
  )
),
