vs code提示flutter sdk没安装

重启一下vs就好了。不知道为啥

vs code版本低，升级不了

需要升级macos。。。。

flutter pub get 不行

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

hover 不能 hotreload

设置了代理

vscode 找不到device

因为flutter进程没杀干净，退了vscode，把flutter杀干净就好了

vscode run 不起来了

一直卡在 launching。。。。。我直接用hover run了，---

custom pallet 可以开启dart log， 需用代理：

[  +14 ms] executing: unzip -t -qq /Users/jinleileiking/lk/flutter/bin/cache/downloads/storage.googleapis.com/flutter_infra/flutter/9a28c3bcf40ce64fee61e807ee3e1395fd6bd954/ios/artifacts.zip

尝试把这个artifacts.zip挪到这个目录，后续又报了一堆错，好像vscode不能用设置的代理，需要改zsh之类的。于是我看了一下ps，把命令弄了出来，试试：

/Users/jinleileiking/lk/flutter/bin/cache/dart-sdk/bin/dart --disable-dart-dev --packages=/Users/jinleileiking/lk/flutter/packages/flutter_tools/.packages /Users/jinleileiking/lk/flutter/bin/cache/flutter_tools.snapshot run --machine --target lib/main.dart -d 23F33AAC-D07A-42D1-93D2-DD35E5A8DB52 --track-widget-creation --dart-define=flutter.inspector.structuredErrors=true --start-paused --web-server-debug-protocol ws --web-allow-expose-url -v

命令复制的不对，还是不行，最终：

在命令行 open /Applications/_green/Visual\ Studio\ Code.app

plugin 找不到 handlefunc

需要再go里面addplugin。。。。

编译出错 [!] Invalid Podfile file: no implicit conversion of nil into String.

ruby太老 -》 rvm 更新 -》 rvm install ruby-head rvm 整了半天，不好使。用rbenv没装成功，最后不用rvm，直接用系统的ruby2.6就好了。。。。

flutter devices 找不到 mi note 3

在手机要打开usb调试。。。。

android 模拟器跑不起来

提示platform version 28没linsence，在sdk manager安装28 platform 的sdk就行了。

Could not resolve all files for configuration ':video_player:androidApis'.

按照：

flutter channel stable
flutter upgrade --force
flutter pub cache repair
cd <YOUR APP FOLDER>
flutter clean

看需要 flutter pub cache repair, 执行后，有的下不下来， 挂全局代理就行了， 非全局不行。。。。。

用环境变量 repair 不行，得挂全局代理。。。。。

还是不行， 然后：

报错：

FAILURE: Build failed with an exception.

最后竟然是android28没装完全。。。。。删了重装就好了。。。沃日。。

android： 不能连接ws

 Fail to connect to service protocol: http://127.0.0.1:64947/z5CsCP5tzD8=/: HttpException: Connection closed before full header was received, uri = http://127.0.0.1:64947/z5CsCP5tzD8=/ws

看了一下，好像是使用stable 导致的，我了个日。。切到beta试试。。。

重启mac。。

取消china flutter 环境变量配置，开启全局代理。

稀里糊涂的好了。。。。

android: exoplayer不能放

报get resoource , 仔细看log是https的事，于是: https://stackoverflow.com/questions/45940861/android-8-cleartext-http-traffic-not-permitted android:usesCleartextTraffic="true" 搞定

最后折腾半天，ios 模拟器[ +545 ms] [VERBOSE-2:ui_dart_state.cc(166)] Unhandled Exception: MissingPluginException(No implementation found for method getData on channel instance.id/go/data)

好像是go只支持桌面，不支持端。。。。。我去，得把go翻译成dart

真不支持：go-flutter-desktop/go-flutter#334

参数pass不过去

参考 https://stackoverflow.com/questions/60395124/flutter-video-player-how-to-add-query-string-parameter-in-network 其实state里可以直接用widget.XXX调用。

video_player不能全屏

换fijkplayer!

列表刷新后，想显示一共有多少条记录
