We're yet to write a backend/business logic in this blog. New line from here // Add Auth Screen on Go Routerīuilder: (context, state) = > const AuthScreen()), Connect Auth Screen to Routerīuilder: (context, state) = > const Home(),īuilder: (context, state) = > const OnBoardScreen()), It's time to add auth_screen to app_router. assets/AuthScreen/WelcomeScreenImage_landscape_2.png Next, is the image section, if you're using the source code from the GitHub repo image should already be in the AuthScreen folder inside assets. That's because gesture detector events should cover the whole visible area which in this case is SingleChildScrollView. You might be wondering why am I using it on auth_screen as a whole instead of auth_form_widget. Together with FocusManager we can track the focus node tree and unfocus the active keyboard. Listener class responds to gesture events like a mouse click, tap, etc. So, we don't need to display user_drawer or the bottom navbar.ĭismissal of the active keyboard, when tapped outside, is an important characteristic to have. Since the app is only accessible to registered users, the authentication screen will be the first screen our users will be prompted to after onboarding. Here is auth_screen, this is it, we'll not make any changes in the future. =// child: SingleChildScrollView(Ĭhild: Image.asset( 'assets/AuthScreen/WelcomeScreenImage_landscape_2.png', OnPointerDown: (PointerDownEvent event) =>įocusManager. =// // to dismiss keyword on tap outside use listener Safe area prevents safe guards widgets to go beyond device edges import 'package:flutter/material.dart' Ĭlass DynamicInputWidget extends StatelessWidget) : super(key: overrideĪppBar: AppBar(title: Text(APP_)), We'll make our dynamic text form widget in text_from_widget file.

For registration, we'll have four inputs: email, username, password, and confirm password inputs, while the sign-in form only uses two inputs: email and password. We'll also write some validations for the input, and animate sign-in registration form transitions. We'll create a dynamic input form widget to be more efficient. In this chapter of the series, we'll create an authentication UI. Among them, Google's Firebase is one of the popular ones, especially for mobile applications. Serverless/Headless apps are on trend these days. Today's blog is one of the most important parts of this blog series as you can tell from the title because now, according to our user-flow screen given below, we have to authenticate the user.Īuthentication is a basic yet very important aspect of any application regardless of platform. So, far in this series, we made Splash Screen, User Onboarding System, Global Theme, and Custom widgets like the app bar, bottom navigation bar, and a drawer for our application. First of all, a special thanks to all the followers and subscribers of this blog series. This is Nibesh from Khadka's Coding Lounge. Hello and welcome to Khadka's Coding Lounge. Create a dynamic Input widget, a form that can transform into both sign-in and registration based on the authentication mode, animate the transition between registration and sign-in form, and validate user input.
