On Xamarin.Forms, you could use Permissions Plugin. https://github.com/jamesmontemagno/PermissionsPlugin

Add permission in Manifest file:

Create a Utils.cs

public static class Utils
{
public static async Task CheckPermissions(Permission permission)
{
    var permissionStatus = await CrossPermissions.Current.CheckPermissionStatusAsync(permission);
    bool request = false;
    if (permissionStatus == PermissionStatus.Denied)
    {
        if (Device.RuntimePlatform == Device.iOS)
        {

            var title = $"{permission} Permission";
            var question = $"To use this plugin the {permission} permission is required. Please go into Settings and turn on {permission} for the app.";
            var positive = "Settings";
            var negative = "Maybe Later";
            var task = Application.Current?.MainPage?.DisplayAlert(title, question, positive, negative);
            if (task == null)
                return permissionStatus;

            var result = await task;
            if (result)
            {
                CrossPermissions.Current.OpenAppSettings();
            }

            return permissionStatus;
        }

        request = true;

    }

    if (request || permissionStatus != PermissionStatus.Granted)
    {
        var newStatus = await CrossPermissions.Current.RequestPermissionsAsync(permission);

        if (!newStatus.ContainsKey(permission))
        {
            return permissionStatus;
        }

        permissionStatus = newStatus[permission];

        if (newStatus[permission] != PermissionStatus.Granted)
        {
            permissionStatus = newStatus[permission];
            var title = $"{permission} Permission";
            var question = $"To use the plugin the {permission} permission is required.";
            var positive = "Settings";
            var negative = "Maybe Later";
            var task = Application.Current?.MainPage?.DisplayAlert(title, question, positive, negative);
            if (task == null)
                return permissionStatus;

            var result = await task;
            if (result)
            {
                CrossPermissions.Current.OpenAppSettings();
            }
            return permissionStatus;
        }
    }

    return permissionStatus;
 }
}

Uasge:

var status = PermissionStatus.Unknown;

    status = await CrossPermissions.Current.CheckPermissionStatusAsync(Permission.Camera);

    if (status != PermissionStatus.Granted)
    {

        status = await Utils.CheckPermissions(Permission.Camera);
    }

Here is a code sample i done before about how to request permission of camera. Xamarin - Requesting camera permissions in WebView
