1.installl flutter
-
中文官网
选择windows平台，我选的zip的stable版本，解压到硬盘，将flutter/bin目录添加到path，并且添加环境变量
PUB_HOSTED_URL=https://pub.flutter-io.cn
FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
FLUTTER_ROOT=D:\Program Files\flutter //flutter安装目录
ANDROID_HOME=D:\Program Files\Android\SDK //Android sdk安装目录
- 运行
flutter docker -v查看当前软件配置是否符合flutter开发的要求，全部调整正确后应显示如下：
E:\Flutter\flutterTest>flutter doctor -v

应全为对号，我未安装Android studio，而是安装的intellij idea，同样可行，device项需要打开emulator才能显示为对号。
- 需要处理的问题主要是Android toolchain，需要在sdkmanager中下载，如下图：
360截图.jpg
不勾选下面的选项，下载26.1.1这个sdk tools，完成后运行flutter doctor --android-licenses，之后的提示全部选择y即可。
- idea需要安装两个插件，flutter和dart插件，有时候会搜索不到插件可以直接到官网下载然后本地安装，flutter插件 dart插件；如果使用的是vscode则到插件栏中下载flutter插件即可，此插件自动关联dart插件。
2.create flutter
- 使用命令或使用idea生成一个新的flutter项目
flutter create flt1， 运行flutter pub get命令将其中使用的库下载下来(有点像npm)，如果下载不了则是上面的环境变量未设置正确。
- 运行
flutter clean清除之前运行的缓存，再运行flutter emulators --launch 虚拟机名称先将emulator运行起来，再运行命令flutter run -v，如果遇到长时间没有变化则应该是gradle的库下载地址有问题，可以换成国内的镜像地址，将\flutter\packages\flutter_tools\gradle下的flutter.gradle文件依赖地址替换掉，如图：
360截图
生成的Android项目内的gradle依赖地址也需要替换。
3.以下是我在vscode内运行的结果，使用idea的运行未成功，命令行没问题：
