我已经完成:
我可以做的所有事情:
flutter clean
,重建flutter pub get
和pod setup
和pod install
flutter upgrade
删除并重新安装颤振,cocoapods,红宝石和飞镖
更改master和dev之间的抖动通道并重复点1。
还尝试使用pub.dev
源和pub.flutter-io.cn
。两者给出相同的结果。
现在在此问题上浪费了2天。所以我怀疑某些软件包或代码可能有问题吗?
感谢您的帮助!谢谢
答案 0 :(得分:0)
最后,我通过以下方法解决了这个问题:
DiagnosticableMixin
中的Diagnosticable
更改为flutter_datetime_picker-1.3.8
说明:显然,正在进行的讨论仍在进行中。文件flutter_datetime_picker-1.3.8.dart
中有一个注释,如下所示:
将DiagnosticableMixin迁移到Diagnosticable,直到 https://github.com/flutter/flutter/pull/51495使其稳定(v1.15.21)
form_builder_chips_input.dart
中注释第95-97行:allowChipEditing: allowChipEditing,
autofocus: autofocus,
focusNode: focusNode,
由于某些未知原因,这三个参数未在ChipsInput
中定义
希望这对某人有帮助,因为我花了一些时间解决了这个问题,因为这些问题来自外部软件包。
