How to remove background color of TextField on Flutter Widget?
You should set filled to true.
TextField(decoration: InputDecoration( fillColor: Colors.red, filled: true)),
Wrap your TextFormField
inside a Container
and change its color
property to match your background color (as from your picture I'll assume its white
):
Container(
color: Colors.white, // or any color that matches your background
child: TextFormField(
decoration: InputDecoration.collapsed(),
validator: (input) => input == "" ? 'The task is empty' : null,
onSaved: (input) => task = input,
)
),
