Complete Source Code

A main.dart file is a file in the Flutter framework that contains the logic for your app. It is the entry point for the application and is where you can define any variables you need to use in your code.

main.dart
import 'package:flutter/material.dart';
import 'package:loginuicolors/login.dart';
import 'package:loginuicolors/register.dart';

void main() {
  runApp(
      MaterialApp(
    debugShowCheckedModeBanner: false,
    home: LoginPage(),
    routes: {
      'register': (context) => RegisterPage(),
      'login': (context) => LoginPage(),
    },
  ));
}
