flutter sdk 版本升級(jí)到2.0或者更高的版本后就發(fā)現(xiàn)運(yùn)行時(shí)會(huì)報(bào)錯(cuò)：
Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:
- package:loading_indicator_view
- package:flutter_swiper
- package:flutter_page_indicator
- package:transformer_page_view
For solutions, see https://dart.dev/go/unsound-null-safety
FAILURE: Build failed with an exception.
也就是說(shuō)以上有些包不支持 safety模式宙枷。
解決方案：--no-sound-null-safety
- 方案一：
通過(guò)命令行運(yùn)行:
- run （debug運(yùn)行）
flutter run --no-sound-null-safety - build （打包apk）
flutter build apk --no-sound-null-safety
- 方案二:
- 也可以在Android studio中設(shè)置運(yùn)行配置。首先打開(kāi)Edit Configurations 頁(yè)面；

- 然后在Additional run args 這行鍵入一下命令:
--no-sound-null-safety
