将MediaQuery textScaleFactor与VR外包装颤动一起使用

Question

我想在我的应用程序中使用textScaleFactor，并且必须在MaterialApp中使用，并且我使用VRouter包，有办法将其与此包一起使用吗

class MyApp extends StatelessWidget {
Future<void> authenticationCheck(BuildContext context,
{VRedirector vRedirector}) async {
if (userRepo.currentUser.value.auth != true) {
// ignore: deprecated_member_use
vRedirector.push('/login',
queryParameters: {'redirectedFrom': '${vRedirector.to}'});
}
}
@override
Widget build(BuildContext context) {
return ValueListenableBuilder(
valueListenable: settingRepo.setting,
builder: (context, Setting _setting, _) {
return VRouter(

这是我的主页，应该遵循的方式如下

return MaterialApp(
builder: (context, child) {
return MediaQuery(
child: child,
data: MediaQuery.of(context).copyWith(textScaleFactor: 0.9),
);
},

应用程序完全建立在此包上，不能更改，有解决方案吗

Answer 1

经过一些研究和实验，我找到了这个解决方案

return ValueListenableBuilder(
valueListenable: settingRepo.setting,
builder: (context, Setting _setting, _) {
return VRouter(
builder: (context, child) {
return MediaQuery(
child: child,
data: MediaQuery.of(context).copyWith(textScaleFactor: 0.9),
);
},

只需在VRouter中使用生成器
