Answer 1

give some padding for container
Container(
padding: EdgeInsets.all(10),
child:TextFormField()
)

Answer 2

Increase the height and width of the container or add padding into the Container
Container(
height: 100.0, // height
width: 400.0, // Width
padding: EdgeInsets.all(10), // Padding
child: TextFormField(),
),
