解决方案 需要安装两个插件:
- Flutter插件： 支持Flutter开发工作流 (运行、调试、热重载等).
- Dart插件： 提供代码分析 (输入代码时进行验证、代码补全等).
要安装这些:
启动Android Studio.
- 打开插件首选项 (Preferences>Plugins on macOS, File>Settings>Plugins on Windows & Linux).
- 选择 Browse repositories…, 选择 Flutter 插件并点击 install.
- 重启Android Studio后插件生效.
具体安装如下：
运行 flutter doctor

[!] IntelliJ IDEA Ultimate Edition (version 2018.2)这个是IntelliJ IDEA编译器，我们只要Android Studio可用就好，大家忽视就好。
