環(huán)境準(zhǔn)備階段：
android-studio 版本：android-studio-ide-191.5977832-windows.exe 3.5.2
flutter版本：stable 版本 （完成系統(tǒng)環(huán)境變量 path配置）
dart版本：2.12.0 （完成系統(tǒng)環(huán)境變量 path配置）
完成相關(guān)軟件安裝。
配置flutter相關(guān)SDK及andriod studio路徑：
flutter config --android-sdk="C:\Users\Administrator\AppData\Local\Android\Sdk"
flutter config --android-studio-dir="D:\Program Files\Android\Android Studio"
執(zhí)行flutter doctor運(yùn)行成功。

夜神模擬器地址：D:\Program Files\Nox\bin （完成系統(tǒng)環(huán)境變量 path配置）
andriod SDK tools：C:\Users\Administrator\AppData\Local\Android\Sdk\platform-tools （完成系統(tǒng)環(huán)境變量 path配置）
nox_adb.exe connect 127.0.0.1:62001
dart SDK:D:\software\dartsdk-windows-x64-release\dart-sdk\bin

將C:\Users\Administrator\AppData\Local\Android\Sdk\platform-tools 下面adb.exe 復(fù)制至D:\Program Files\Nox\bin覆蓋
adb.exe，此外重新復(fù)制adb.exe命名為nox_adb.exe，替換原有的nox_adb.exe。
cdm 輸入nox_adb version 及adb version發(fā)現(xiàn)版本一致。

啟動(dòng)野神模擬器，輸入adb devices發(fā)現(xiàn)虛擬設(shè)備，執(zhí)行flutter devices發(fā)現(xiàn) 127.0.0.1:62001 設(shè)備。
