Mac端dart环境搭建和第一个Dart程序

安装Dart Sdk

Dart Sdk用来开发web和服务器端,如果开发移动app直接使用flutter就可以了.
下面是mac下搭建Dart教程

• 安装 Dart Sdk

brew tap dart-lang/dart
brew install dart

• 升级 Dart

brew upgrade dart

• 查看安装信息

brew info dart

安装上面成功安装后,查看dart的安装信息如下:

yumodeMacBook-Pro:flutter yumo$ brew info dart

IntelliJ IDEA

安装Dart插件

打开Preferences安装Dart插件,插件安装后重启Intellij IDEA使之Dart插件生效.

创建Dart工程

新建Dart工程,选择Console Application-ccommand-line application sample类型

执行demo

创建工程完成后,自动创建了一个main.dart实例程序,运行后输出42

• /bin/mart.dart文件

import 'package:dart/dart.dart' as dart;

main(List arguments) {
  print('Hello world: ${dart.calculate()}!');
}

• /lib/dart.dart

import 'package:dart/dart.dart' as dart;

main(List arguments) {
  print('Hello world: ${dart.calculate()}!');
}

输出Hello world

在bin目录下面创建hello.dart文件

main(){
  var hello = "hello world";
  print(hello);
}

运行该文件后输出为:

/usr/local/opt/dart/libexec/bin/dart --enable-asserts --enable-vm-service:60162 /Users/yumo/git/gits/dart/bin/hello.dart
Observatory listening on http://127.0.0.1:60162/Ozzxrn1Y2IQ=/

hello world

Process finished with exit code 0
