Flutter 環(huán)境變量配置編輯.bash_profile文件
一伯铣、編輯.bash_profile文件
啟動iTerm 或者 Terminal終端工具，終端命令進入自己用戶名下虎眨，查看是否存在隱藏文件bash_profile，
? ~ cd ~/
? ~ ls -a
如果沒有則創(chuàng)建一個隱藏文件.bash_profile，
? ~ touch .bash_profile
如果存在婿失，若只是查看輸入open ~/.bash_profile打開嫩痰，若是編輯open -e ~/.bash_profile打開
? ~ open ~/.bash_profile
? ~ open -e ~/.bash_profile
編輯后
# HomeBrew

export PATH="/usr/local/bin:$PATH"
export PATH="/usr/local/sbin:$PATH"

注意：
（1）Android 環(huán)境變量ANDROID_HOM替換自己Android SDK的sdk存放路徑剿吻，可去資源庫下查看我的Android SDK的sdk存放路徑/Users/cosmo/Library/Android/sdk
（2）Android tools路徑可在資源庫目錄下Android/sdk/build-tools/查看實際的構(gòu)建版本文件名做相應(yīng)修改比如填寫30.0.328.0.3
（3）由于在國內(nèi)訪問Flutter可能會受到限制，F(xiàn)lutter官方為中國開發(fā)者搭建了臨時鏡像串纺，可以將
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
環(huán)境變量加入到用戶環(huán)境變量中丽旅，此鏡像為臨時鏡像，并不能保證一直可用纺棺，大家可以從 Using Flutter in China 上獲得有關(guān)鏡像服務(wù)器的最新動態(tài)榄笙。
二、驗證.bash_profile文件
.bash_profile編輯結(jié)束后保存祷蝌，iTerm 或者 Terminal終端工具輸入source .bash_profile命令可更新剛配置的環(huán)境變量即時生效
? ~ source .bash_profile
在終端Terminal或者iTerm輸入flutter doctor進行檢查茅撞。

Android Studio已經(jīng)安裝Flutter和Dart插件，項目正常運行flutter doctor依然報

最新Android Studio毛病多，略之米丘。
即ok

1.更新flutter最新穩(wěn)定版本剑令，如果出現(xiàn)
? ~ flutter doctor

需要有效網(wǎng)絡(luò)，然后再次運行即可
