记录在学习Flutter中遇到的问题，并没有模块化的文章。
1. pubspec.yaml文件引入库
-
错误：
pubspec.yaml文件中引入网络库报错。 -
错误日志：
packages get
Running "flutter packages get" in flutter_demo...
Error on line 21, column 5 of pubspec.yaml: A dependency may only have one source.
sdk: flutter
^^^^^^^^^^^^^
pub get failed (65)
- 错误原因：
在引入http库，没有注意到空格。
dependencies:
flutter:
sdk: flutter
http: ^0.12.0
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^0.1.2
- 修正
注意引入库文件位置，以及空格。
dependencies:
flutter:
sdk: flutter
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^0.1.2
http: ^0.12.0
2. 库文件无法更新，或者无法其他操作
- 错误：
Waiting for another flutter command to release the startup lock...
- 错误原因：
由于工程闪退，或者在进行一个操作的同时进行了其他操作，导致文件被锁。 - 解决办法：
删除~/flutter/bin/cache/lockfile文件。
3. Flutter启动Xcode,以及安装到移动端调试
- 启动
Xcode
在编辑器终端(Terminal)输入open ios/Runner.xcworkspace/ -
Android Studio直接安装release到移动设备
在编辑器终端(Terminal)输入flutter run --release
More than one device connected; please specify a device with the '-d <deviceId>' flag, or use '-d all' to act on all devices.
“***”的 iPhone • 24e**********7cb1 • ios • iOS 12.1.4
iPhone XR • 3A0**********F24C • ios • iOS 12.1 (simulator)
// 说明有两个设备同时打开，我们需要选中其中一个运行
flutter run --release -d 24e**********7cb1 // 运行到真机上
4. 直接启动Xcode然后选中release环境会报错

========================================================================
ERROR: Flutter does not support running in profile or release mode on
the Simulator (this build was: 'release').
You can ensure Flutter runs in Debug mode with your host app in release
mode by setting FLUTTER_BUILD_MODE=debug in the .xcconfig associated
with the Release build configuration.
