Mi android manifest.xml no reconoce los permisos - flutter

Question

I have an app that uses a qrscan to obtain data and then does a service with the scanned data, the first time I tested it on a Redmi 9 if it asked for later permissions with other devices it no longer asked me for permissions, asking for the correct functioning of the library
this is my manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app_roja_rastreo_update">
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<application
android:label="app_roja_rastreo_update"
android:icon="#mipmap/ic_launcher">
<activity
android:name=".MainActivity"
android:launchMode="singleTop"
android:theme="#style/LaunchTheme"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize">
<!-- Specifies an Android theme to apply to this Activity as soon as
the Android process has started. This theme is visible to the user
while the Flutter UI initializes. After that, this theme continues
to determine the Window background behind the Flutter UI. -->
<meta-data
android:name="io.flutter.embedding.android.NormalTheme"
android:resource="#style/NormalTheme"
/>
<!-- Displays an Android View that continues showing the launch screen
Drawable until Flutter paints its first frame, then this splash
screen fades out. A splash screen is useful to avoid any visual
gap between the end of Android's launch screen and the painting of
Flutter's first frame. -->
<meta-data
android:name="io.flutter.embedding.android.SplashScreenDrawable"
android:resource="#drawable/launch_background"
/>
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<!-- Don't delete the meta-data below.
This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
<meta-data
android:name="flutterEmbedding"
android:value="2" />
</application>
</manifest>
Try to use permission_handler in my code, to force the user to activate the permissions
but the console gave me this:
V/BoostFramework(28768): mAcquireFunc method = public int com.qualcomm.qti.Performance.perfLockAcquire(int,int[])
V/BoostFramework(28768): mReleaseFunc method = public int com.qualcomm.qti.Performance.perfLockRelease()
V/BoostFramework(28768): mAcquireTouchFunc method = public int com.qualcomm.qti.Performance.perfLockAcquireTouch(android.view.MotionEvent,android.util.DisplayMetrics,int,int[])
V/BoostFramework(28768): mIOPStart method = public int com.qualcomm.qti.Performance.perfIOPrefetchStart(int,java.lang.String)
V/BoostFramework(28768): mIOPStop method = public int com.qualcomm.qti.Performance.perfIOPrefetchStop()
V/BoostFramework(28768): BoostFramework() : mPerf = com.qualcomm.qti.Performance#4363c91

D/permissions_handler(28768): No permissions found in manifest for: []2
my code with the use of permission handler
#override
Widget build(BuildContext context) {
return GestureDetector(
onTap: () async {
var status = await Permission.camera.status;
//await Permission.contacts.request();
if(status.isDenied|| status.isRestricted||status.isPermanentlyDenied){
await Permission.contacts.request();
}
if (await Permission.contacts.request().isGranted) {
processQuery(context, await getCode());
}
},
