Flutter 版本更改后，英雄小部件不能是另一个英雄小部件的后代
我最近尝试添加firebase fcm，但它不起作用，只是导致了几个错误，因此我将所有内容回滚到原始运行代码，但在此过程中升级了Flitter…因为1.3.10版英雄不能在其子层次结构中包含另一个英雄小部件，但我找不到修复程序。（理想情况下，不希望将版本更改回原来的版本） 我检查了heroTags，也找不到任何嵌套的Hero小部件-可能是因为动画生成器Flutter 版本更改后，英雄小部件不能是另一个英雄小部件的后代,flutter,dart,flutter-animation,Flutter,Dart,Flutter Animation,我最近尝试添加firebase fcm，但它不起作用，只是导致了几个错误，因此我将所有内容回滚到原始运行代码，但在此过程中升级了Flitter…因为1.3.10版英雄不能在其子层次结构中包含另一个英雄小部件，但我找不到修复程序。（理想情况下，不希望将版本更改回原来的版本） 我检查了heroTags，也找不到任何嵌套的Hero小部件-可能是因为动画生成器 import 'package:flutter/material.dart'; import 'dart:math'; import 'pack

要解决此问题，您只需将晶圆厂中的“heroTag”属性设置为“null”，或删除晶圆厂周围的包装Hero小部件，只保留默认值。此问题的简单解决方案是使用堆栈并重叠这些Hero小部件，这样Hero小部件将不再是Hero小部件的子部件，但是请记住，这两个英雄小部件的标签应该是不同的！ 希望这对你有帮助
