遇到过类似的情况， 我们App的结构是首页tabhost添加了四个Fragment， 第三个tab中嵌入了Flutter，使用Viewpager+Fragment+FlutterBoostFragment，在Flutter中点击打开原生页面，返回应该会回到当前FlutterboostFragment，实际上却变成了其他的FlutterBoostFragment，断点发现，返回后，FlutterBoost会同时触发多个Fragment的onresume或setUserVisibleHint

目前我们是这么处理的，但还会有其他问题，比如闪现其他FlutterBoostFrament，再显示当前FlutterBoostFragment //继承FlutterBoostFragment override fun onResume() { super.onResume() if (parentFragment?.isHidden == true || isHidden) { return; } if (userVisibleHint) { Handler().postDelayed({ onHiddenChanged(false) }, 0) } }

在Pixel 4a上测试没有复现问题。@ynnekj 你用什么手机测试的？

demo.mp4 在Pixel 4a上测试没有复现问题。@ynnekj 你用什么手机测试的？

flutter doctor -v

用了几部手机测试

下面 3 部显示正常： • M2012K11AC (mobile) • 7e09e08 • android-arm64 • Android 11 (API 30) • Redmi K20 Pro Premium Edition (mobile) • 77c468fb • android-arm64 • Android 11 (API 30) • TNY AL00 (mobile) • RPG0218B23003909 • android-arm64 • Android 10 (API 29)

下面 3 部 Galaxy S9、Galaxy S8、OPPO 都出现了这个问题： • SM G960U (mobile) • 4749475233343098 • android-arm64 • Android 8.0.0 (API 26) • SM G9500 (mobile) • 9887bc355545493748 • android-arm64 • Android 7.0 (API 24) • PBAM00 (mobile) • 4e7cd684 • android-arm64 • Android 8.1.0 (API 27)

可能是 Android 8.1.0 (API 27) 以下版本会出现问题。
