In this article, we are going to create a minimal custom Switch Widget in Flutter. Flutter provides a built-in “Switch Widget” which looks simple. We are going to create our own “Flat Style” switch widget.

The switch has two parts:

  • The base
  • The knob

We will start writing code for the base and the knob separately.

Base

The base is nothing but the background of the switch which is in a rounded rectangle shape.

Widget for Switch Base

  1. *AnimatedContainer *is used instead of container because we are going to add animations when the switch is turned ON and OFF.
  2. *widget.value *holds either *true *or *false *which represents whether a switch is *ON *or *OFF *respectively

The Knob

The knob is the *circular *button inside the base that we use to toggle the state of the switch.
