User Interface Design - Part 1

In Flutter, UI design involves creating visual and interactive elements for your app using widgets. Widgets are pre-built components that can be arranged in a hierarchy to create complex layouts. Tools and libraries such as Material Design and Cupertino can help you design and build beautiful looking UIs.

Tips

• Use Image.network to display your image.
• Widgets Container, Text, ElevatedButton, IconButton, Container, Stack, Row and Column
• Don’t forget to post screenshot after you are done to your social networks with hashtag #30DaysMasterFlutter

By the end of this day, you should have a basic understanding of how to use widgets to create custom layouts and designs.

Tips

• To understand Flutter’s building blocks, which are widgets, it’s important to review the basics of Dart, particularly its OOP (Object-Oriented Programming) concepts. Widgets are essentially classes, so having a good grasp of OOP in Dart is crucial. You can improve your understanding by practicing and building more projects.
• Experiment with different widgets, such as the Text, Container, Row, and Column widgets, to create layouts and designs.
• Containers are used to wrap other widgets and provide a way to add padding, margins, and other styling. Rows and columns are used to arrange other widgets in a horizontal or vertical direction.
• A simple app with a custom layout using basic widgets

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'My App',
      home: Scaffold(
        appBar: AppBar(
          title: Text('My App'),
        ),
        body: Container(
          padding: EdgeInsets.all(16.0),
          child: Column(
            children: <Widget>[
              Image.network(FlutterLogo()),
              SizedBox(height: 16.0),
              Text(
                'Welcome to my app!',
                style: TextStyle(fontSize: 24.0),
              ),
              SizedBox(height: 16.0),
              Row(
                mainAxisAlignment: MainAxisAlignment.spaceEvenly,
                children: <Widget>[
                  RaisedButton(
                    child: Text('Button 1'),
                    onPressed: () {},
                  ),
                  RaisedButton(
                    child: Text('Button 2'),
                    onPressed: () {},
                  ),
                ],
              ),
            ],
          ),
        ),
      ),
    );
  }
}
