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 dart-lang/dart/dart: stable 2.3.1, devel 2.3.2-dev.0.0 The Dart SDK https://www.dartlang.org/ /usr/local/Cellar/dart/2.3.1 (367 files, 409.7MB) * Built from source on 2019-05-26 at 08:59:06 From: https://github.com/dart-lang/homebrew-dart/blob/master/dart.rb ==> Options --devel Install development version 2.3.2-dev.0.0 ==> Caveats Please note the path to the Dart SDK: /usr/local/opt/dart/libexec

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<String> arguments) { print('Hello world: ${dart.calculate()}!'); } /lib/dart.dart import 'package:dart/dart.dart' as dart; main(List<String> 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
