                      permission != Permission.audio &&
                      permission != Permission.scheduleExactAlarm &&
                      permission != Permission.sensorsAlways;
                })
                .map((permission) => PermissionWidget(permission))

              )
              : null,
      onTap: () {
        requestPermission(widget.permission);

```

--------------------------------

### Open App Settings

Source: https://pub.dev/packages/permission_handler

Open the application's settings page in the system settings. This is useful when a permission is permanently denied and requires manual user intervention.

```dart
if (await Permission.speech.isPermanentlyDenied) {
  // The user opted to never again see the permission request dialog for this
  // app. The only way to change the permission's status now is to let the
  // user manually enables it in the system settings.
  openAppSettings();
}
```

--------------------------------

### Enable AndroidX and Jetifier

Source: https://pub.dev/packages/permission_handler

Add these lines to your 'gradle.properties' file to ensure compatibility with AndroidX and Jetifier.

```properties
android.useAndroidX=true
android.enableJetifier=true
```

### Request Permission with Callbacks

Source: https://pub.dev/packages/permission_handler

Request a permission and define callbacks for different permission status changes. This allows for immediate feedback or actions when a permission is granted, denied, permanently denied, restricted, limited, or provisional.

```dart
await Permission.camera
  .onDeniedCallback(() {
    // Your code
  })
  .onGrantedCallback(() {
    // Your code
  })
  .onPermanentlyDeniedCallback(() {
    // Your code
  })
  .onRestrictedCallback(() {
    // Your code
  })
  .onLimitedCallback(() {
    // Your code
  })
  .onProvisionalCallback(() {
    // Your code
  })
  .request();
```

--------------------------------

### Configure iOS Permissions in Podfile

Source: https://pub.dev/packages/permission_handler

Modify your 'Podfile' to enable specific iOS permissions by uncommenting the relevant macros. This is crucial for static code analysis during app submission.

```ruby
post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)

    target.build_configurations.each do |config|
      # You can remove unused permissions here
      # for more information: https://github.com/Baseflow/flutter-permission-handler/blob/main/permission_handler_apple/ios/Classes/PermissionHandlerEnums.h
      # e.g. when you don't need camera permission, just add 'PERMISSION_CAMERA=0'
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',

  }

  void _listenForPermissionStatus() async {
    final status = await _permissionHandler.checkPermissionStatus(_permission);
    setState(() => _permissionStatus = status);
  }

  Color getPermissionColor() {
    switch (_permissionStatus) {
      case PermissionStatus.denied:
        return Colors.red;
      case PermissionStatus.granted:
