Flutter-5: flutter Error 处理

1: Waiting for another flutter command to release the startup lock...

# 进入flutter代码、删除lockfile文件:/Applications/flutter/bin/cache/lockfile

2: Error installing libwebp

[!] Error installing libwebp
[!] /usr/bin/git clone https://chromium.googlesource.com/webm/libwebp /var/folders/1v/400l8skj553411yykclk7myw7ch02d/T/d20200619-30142-ahlxb5 --template= --single-branch --depth 1 --branch v1.1.0

Cloning into '/var/folders/1v/400l8skj553411yykclk7myw7ch02d/T/d20200619-30142-ahlxb5'...
fatal: unable to access 'https://chromium.googlesource.com/webm/libwebp/': Failed to connect to chromium.googlesource.com port 443: Operation timed out

# 解决方案:
- 进入：/Users/qxu7859/.cocoapods/repos/cocoapods/Specs/1/9/2/libwebp
- 根据报错打开对应版本如v1.1.0
- open libwebp.podspec.json
- 将scource = "https://chromium.googlesource.com/webm/libwebp" 替换为 “https://github.com/webmproject/libwebp.git”即可

- 重新执行pod install就可以了。

3: Secrets.xcconfig

1: error: /Users/qxu7859/Desktop/mobile-connected/ios/Flutter/bmwnorthamericadevelopment.xcconfig:4: could not find included file 'Secrets.xcconfig' in search paths (in target 'Runner' from project 'Runner')

# 解决方案
- 将Secrets.xcconfig文件内容清空
- 由于Secrets.xcconfig这个文件是灰色的、在show in finder里面找不到这个文件实体、需要copy一个空的同名的这个文件放在show in finder里面
- 重启Xcode

# 注意
- 真机编译某一个版本的时候、Scheme 和 Capablity 这两个地方的选择环境需要一致性
