In this article, we will go through a detailed explanation and implementation of Flutter appbar leading. We’ll first see what it is and then we’ll customize it.
Introduction: Flutter Appbar Leading
Leading in appbar can be an icon, image, text or other widget in the Flutter appbar.
If you have navigated from one screen to another screen and in the second one, you have defined a flutter appbar then on the left side of the flutter appbar, you will see an arrow flutter icon which if get clicked then it navigates to the previous screen. Let’s understand it using practical code implementations.
