In this article, we’re going to create a very simple flutter project called “Hello World”. If you don’t have an environment setup, feel free to check flutter documentation first
Creating your first project
flutter create firstapp
cd firstapp
Editing /lib/main.dart
main.dart is a file that executes for the first time when you open an app. Like a C-Program, Dart also starts with main() as an initial function to execute. inside main() we need to return a runApp() with widgets This example, we have returned a simple Widget called Text()
Text Widget contains a few properties such as string, alignments, directions ..etc.(check out: https://docs.flutter.io/flutter/widgets/Text-class.html)
Final Code
import 'package:flutter/material.dart';
void main(){
return runApp(Text('Hello World', textDirection: TextDirection.ltr));
}
Since, main() return only one function, we can simplify this code as follow
import 'package:flutter/material.dart';
void main() => runApp(Text('Hello World', textDirection: TextDirection.ltr));
