Error in the method for uploading an image with firebase - xamarin

Question

I have a problem when i going to upload an image in my database tha is in Firebase.
This is my view xaml called: InitialPage
<StackLayout Grid.Row="0">
<Image Source="{Binding Icon}"/>
<Button Text="Add Image"
Command="{Binding ImageDataCommand}"/>
</StackLayout>
I have a button called ImageDataCommand that, when i select searches for the image in the phone gallery show an error in
Icon.Source
private string _icon;
public string Icon
{
get { return _icon; }
set
{
_icon = value;
RaisePropertyChanged();
}
}
public ICommand ImageDataCommand => new Command(async (s) => await InsertImage(s));
private async Task InsertImage(object s)
{
await CrossMedia.Current.Initialize();
try
{
file = await CrossMedia.Current.PickPhotoAsync(new PickMediaOptions()
{
PhotoSize = PhotoSize.Medium
});
if (file == null)
return;
Icon.Source = ImageSource.FromStream(() =>
{
var imageStream = file.GetStream();
return imageStream;
});
}
catch (Exception ex)
{
Debug.WriteLine(ex);
}
}
I'm using FreshMvvm and i see that one way is use x:name but in my InitPageModel not shown.
I am starting to use Freshmvvm to avoid putting code in the .cs files of classes or views.
greetings

Change Icon from string to ImageSource .
private ImageSource _icon;
public ImageSource Icon
{
get { return _icon; }
set
{
_icon = value;
RaisePropertyChanged();
}
}
Set Icon directly after getting the image from gallery .
Icon = ImageSource.FromStream(() =>
{
var imageStream = file.GetStream();
return imageStream;
});
