Error en Android 12 (API level 31) FLAG_IMMUTABLE or FLAG_MUTABLE

[Rigo09]

Hola! muchas gracias por tu aporte @acaliaro, en este momento intenté probarlo y me generaba el error:
Java.Lang.IllegalArgumentException: 'com.companyname.mauiapptestnfcandroid: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.'

para solucionarlo sustituí en el MainActivity.cs
var pendingIntent = PendingIntent.GetActivity(this, 0, intent, 0);
por
var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.Immutable);

Hi @acaliaro I'm learning from your project MauiAppTestNfcAndrid. I'm new to .net development and I working with a .net Maui Blazor type project . I tried to test the application but still don't have the ReadPage view and its viewmodel. My question is the following: From the XamarinDemoNFC project, can I bring the pages that already existed, for example ReadPage.xaml, and add them to the Maui project to test reading an NFC tag?
