模态底部图纸库导致问题

Question

我今天升级了我的 flutter 版本并发现了这个问题：

../../../../../AppData/Local/Pub/Cache/hosted/pub.dev/modal_bottom_sheet-2.1.2/lib/src/bottom_sheets/bar_bottom_sheet.dart:102:13: Error: 'ModalBottomSheetRoute' is imported from both 'package:flutter/src/material/bottom_sheet.dart' and 'package:modal_bottom_sheet/src/bottom_sheet_route.dart'.

它在我尝试调试它后出现，是否有任何解决方案或者我应该删除这个库？

Answer 1

所以这个问题是由于 flutter 3.7 和 modal_bottom_sheet:2.1.0 中的名称冲突造成的

自从 flutter 3.7 发布这个编译时问题开始以来，库维护者已经发布了3.0.0-pre版本，他们将任何ModalBottomSheetRoute类引用重命名为ModalSheetRoute. 使用这个版本modal_bottom_sheet: ^3.0.0-pre

Answer 2

升级 flutter 后我也遇到了同样的问题。我意识到是flutter开发环境的兼容性问题。解决方案是还更新开发通道：

flutter channel dev
flutter upgrade

Answer 3

根据Ashish的说法，对我有用的是，我通过添加以下行，在 pubspec.yaml 文件中使用依赖项覆盖对默认模式底部表进行了覆盖：

dependency_overrides:
  modal_bottom_sheet: ^3.0.0-pre

（添加到 pubspec.yaml 文件时请务必检查缩进）
