Introduction: Flutter Login And Registration Template Design
We’ve created this beautiful Flutter login and registration template design by using multiple Flutter widgets. We’ve created a toggle which can be used to show login or registration form.
Widgets that are used in creating this amazing Flutter login and registration template UI design are listed below:
- Flutter Column Widget
- Flutter Row Widget
- Flutter Gradient Container Widget
- Flutter Textfield Widget
- Flutter Gesture Detector Widget
- Flutter Inkwell Widget
- Flutter Text Widget
- Flutter Single Child Scroll View Widget
- Flutter Padding Widget
- Flutter Snackbar Widget
- Flutter Container Widget
I’ve written detailed articles on the widgets listed above, you can check them out using the menu bar or search box of this site.
The complete source code of this beautiful Flutter login and registration template UI is available in the below section.
Try to understand how every Flutter widget is doing its role in this beautiful login and registration UI design and implement this design from scratch.
You can paste this code inside your main file. No additional packages required. Hope you’ll like it. Also, try to customize it according to your set of requirements.
