Flutter -- 环境搭建

字数 216阅读 3376

一、环境搭建

1.克隆项目

git clone -b beta https://github.com/flutter/flutter.git

2.将flutter加入path(让在任何目录下都可调用flutter)

打开.bash_profile(一般在Mac的当前用户目录下),编辑添加

export PATH=[克隆项目的目录]/flutter/bin:$PATH
cenghaihandeMacBook-Pro:~ catchzeng$ vim ~/.bash_profile
[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*


# added by Anaconda2 5.1.0 installer
export PATH="/Users/catchzeng/anaconda2/bin:$PATH"

export PATH=/Users/catchzeng/flutter/bin:$PATH

运行source刷新

source ~/.bash_profile

验证PATH是否包含了flutter

cenghaihandeMacBook-Pro:~ catchzeng$ echo $PATH
/Users/catchzeng/flutter/bin:/Users/catchzeng/anaconda2/bin:

3.安装iOS环境依赖

$ brew install --HEAD libimobiledevice
$ brew install ideviceinstaller ios-deploy cocoapods

4.安装 VS Code

https://code.visualstudio.com

5.安装dart code

dart code

6. 运行flutter doctor,验证是否有错误

cenghaihandeMacBook-Pro:~ catchzeng$ flutter doctor
Doctor summary (to see all details, run flutter doctor -v):

二、新建项目

1.调出命令行面板(快捷键Command+Shift+P),输入flutter选择Flutter: New Project,回车,输入项目名并选择保存路径

2.确认设备连接

3.打开项目目录下的ios/Runner.xcworkspace,并修改签名信息

4.按下F5开始Debug调试

5.随意修改main.dart,然后Command+s保存,便能看到效果,这就是Flutter的热加载,方便调试

mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            new Text(
              'You have pushed the button this many times 测试:',
            ),
            new Text(
              '$_counter',
              style: Theme.of(context).textTheme.display1,
            ),
          ],
Demo
