一、基本安裝按照官網文檔即可
https://flutter.io/docs/get-started/install/windows
flutter目前在快速迭代中，建議直接同步github上的代碼即可
因爲通過release的包安裝的版本，也就是一個git庫
二、我的安裝環境爲
windows 7 + vs code + android sdk
我也安裝了android studio，實際可以不必安裝
三、通過命令 flutter doctor 檢查是否配置成功
問題一：提示No devices available
就是沒有找到設備，可以用實體機，也可以用模擬器，用AVD Manager創建一個。
我是用Genymotion來創建的，相對資源佔用少一點（注：Genymotion的鏡像下載很慢，可以到C:\Users\xx\AppData\Local\Genymobile\genymotion.log裏獲得下載的地址，通過下載工具下載後，複製到C:\Users\xx\AppData\Local\Genymobile\Genymotion\ova下，即可）
問題二：X Android license status unknown.
[flutter] flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel stable, v1.0.0, on Microsoft Windows [Version 6.1.7601], locale zh-CN)
[!] Android toolchain - develop for Android devices (Android SDK 28.0.3)
X Android license status unknown.
[√] Android Studio (version 3.2)
X Flutter plugin not installed; this adds Flutter specific functionality.
X Dart plugin not installed; this adds Dart specific functionality.
[√] VS Code (version 1.30.1)

這個提示最碰到的，也最麻煩，查找flutter的github上的issues，一般的回答都是用flutter doctor --android-licenses，正常情況下是可以，類似這樣，一路就可以了
C:\Users\xx>flutter doctor --android-licenses
Warning: Observed package id 'build-tools;28.0.0-rc2' in inconsistent location 'D:\PlatformSDKs\android-sdk-windows\build-tools\28.0.0-preview' (Expected 'D:\PlatformSDKs\android-sdk-windows\build-tools\28.0.0-rc2')
Warning: Observed package id 'tools' in inconsistent location 'D:\PlatformSDKs\android-sdk-windows\tools2' (Expected 'D:\PlatformSDKs\android-sdk-windows\tools')

5 of 6 SDK package licenses not accepted. 100% Computing updates...
Review licenses that have not been accepted (y/N)? y
但很多情況是這樣的
C:\Users\95>flutter doctor --android-licenses
A newer version of the Android SDK is required. To update, run:
D:\PlatformSDKs\android-sdk-windows\tools\bin\sdkmanager --update
接着按提示輸入 sdkmanager --update
C:\Users\xx>D:\PlatformSDKs\android-sdk-windows\tools\bin\sdkmanager --update
Warning: Observed package id 'build-tools;28.0.0-rc2' in inconsistent location 'D:\PlatformSDKs\android-sdk-windows\build-tools\28.0.0-preview' (Expected 'D:\PlatformSDKs\android-sdk-windows\build-tools\28.0.0-rc2')
Warning: Observed package id 'build-tools;28.0.0-rc2' in inconsistent location 'D:\PlatformSDKs\android-sdk-windows\build-tools\28.0.0-preview' (Expected 'D:\PlatformSDKs\android-sdk-windows\build-tools\28.0.0-rc2')
Warning: An error occurred during installation: Failed to move away or delete existing target file: D:\PlatformSDKs\android-sdk-windows\tools
Move it away manually and try again..
done
會報錯，是因爲執行sdkmanager --update會重新創建一個tools目錄。所以要改名當前的tools目錄，再執行sdkmanager --update即可。另外android-sdk需要更新包，要事先更新，比如上面提示的28.0.0.rc2
四、再次執行flutter doctor
[flutter] flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel stable, v1.0.0, on Microsoft Windows [Version 6.1.7601], locale zh-CN)
[√] Android toolchain - develop for Android devices (Android SDK 28.0.3)
[√] Android Studio (version 3.2)
X Flutter plugin not installed; this adds Flutter specific functionality.
X Dart plugin not installed; this adds Dart specific functionality.
[√] VS Code (version 1.30.1)
[√] Connected device (1 available)
• No issues found!
exit code 0
就提示 no issues了，我暫沒有用android studio做flutter項目，不理android studio的提示
五、創建第一個項目 https://flutter.io/docs/get-started/test-drive?tab=vscode
問題一：第一個創建項目編譯比較慢，主要是要下載gradle庫，庫相對大一點，很可能會超時
Exception in thread "main" java.lang.RuntimeException: Timeout of 120000 reached waiting for exclusive access to file: C:\Users\xx\.gradle\wrapper\dists\gradle-4.10.2-all\9fahxiiecdb76a5g3aw9oi8rv\gradle-4.10.2-all.zip
C:\Users\xx\.gradle\wrapper\dists 這個目錄有自動下載各種版本的gradle包。
你可以更改，gradlew.bat中的set CLASSPATH=%APP_HOME%\gradle\wrapper\gradle-wrapper.jar 爲某一個grable版本
你也可以多試幾次，或者手動下載gradle-4.10.2-all.zip，然後複製到上面的目錄中
比如
https://downloads.gradle.org/distributions/gradle-4.10.2-all.zip
問題二：E/flutter ( 2578): [ERROR:flutter/shell/gpu/gpu_surface_gl.cc(85)] Failed to setup Skia Gr context.
發現設備的android api版本小於19，就會報這個錯誤，也就是android的版本要4.4版以上
看了github上的issues，應該是一個bug，社區已發現這個bug，應該不久就會修復了
