我尝试过清理项目、升级 pub 包和 flutter pub 缓存修复，但它仍然是一样的。我还可以使用其他解决方案吗？

\n

Answer 1

使用更新的插件

更换旧的：

  flutter_datetime_picker: ^1.5.1

致新人：

  flutter_datetime_picker_plus: ^2.1.0

导入示例

进口

import 'package:flutter_datetime_picker_plus/flutter_datetime_picker_plus.dart' as datatTimePicker;

Answer 2

在您的ChipsInput小部件中，您使用了 2 个相互冲突的导入。您调用的位置会发生冲突，this.theme = theme ?? DatePickerTheme()因为它不知道要使用哪个导入，因为它们具有相同的名称。

您需要删除import 'package:flutter/src/material/date_picker_theme.dart' 或import 'package:flutter_datetime_picker_bdaya/src/datetime_picker_theme.dart'

as或者，您可以尝试使用以下命令重命名其中 1 个导入：

import 'package:flutter_datetime_picker_bdaya/src/datetime_picker_theme.dart' as example

example.DatePickerTheme()
