1 ? 在運行flutter doctor忘晤，出現(xiàn)以下錯誤：
[?] Flutter (on Linux, locale en_US.UTF-8, channel master)
[?] Android toolchain - develop for Android devices
? Unable to locate Android SDK.
Install Android Studio from:https://developer.android.com/studio/index.html
On first launch it will assist you in installing the Android SDK components.
(or visithttps://flutter.io/setup/#android-setupfor detailed instructions).
If Android SDK has been installed to a custom location, set $ANDROID_HOME to that location.
[?] Android Studio (version 3.0.0)
? Android Studio at /home/f/App/android-studio
? Gradle version 3.2
? Java version OpenJDK Runtime Environment (build 1.8.0_112-release-b06)

解決方法：
添加環(huán)境變量ANDROID_HOME，把你android SDK的路徑填上，重啟電腦即可郁妈。
