Unhandled Exception while using FontAwesomeWeb (ttf) version 5.3.1

[npagare]

Describe the bug Hi @wilsonvargas, thank you for helping us with this great plugin. To make use of font icons from the latest version (53.1) of FontAwesomeWeb (ttf) filesI updated the my App's info.plist file as below. fa-solid-900.ttf fa-regular-400.ttf fa-brands-400.ttf MaterialIcons-Regular.ttf

But while testing my changes with ButtonCirclePlugin using FontAwesomeWeb v5.3.1 I am getting unhandled exception error as shown below.

Can you please confirm if your codebase is tied only to your version of the Font Awesome and Material ttf files? <cFAB:CircleButton IsVisible="True"
Grid.Row="0" Grid.Column="1" x:Name="fabRound"
FontIcon="FontAwesome" <=== this is a as is enum from your code. How does it read the key value from about updates in the info.plist? It doesn't throw any error when using around MaterialIcon even when my value in the info.plist is as shown above Icon="fa-bed"
FontSize="15" TextColor="WhiteSmoke" HeightRequest="35" WidthRequest="35" BorderThickness="5" BorderColor="Red" BackgroundColor="White" Clicked="Clicked"/>

To Reproduce Steps to reproduce the behavior:

1. Go to '...' Download latest FontAwesomeWeb v5.3.1 font file

2. Click on '....' unzip the downloaded file. Copy all 3 ttf files from {downloadfolder\fontawesome-free-5.3.1-web\fontawesome-free-5.3.1-web\webfonts} in your iOS app's resources folder. Use https://github.com/smourier/FontAwesomeEnum to create a fontAwesomeWeb Enum class. I have a attached .cs file that has new enums and literals defined for version 5.3.1. Remove the .txt extension to get to .cs file. FontAwesomeWeb531Font.cs.txt

3. Scroll down to '....' Update your info.plist as shown above 3.1 in App.xaml include following resource declarations

   <Application.Resources>

    <ResourceDictionary>
        <OnPlatform 
    		x:Key="FontAwesomeWeb531SIconsFontFamily" 
            x:TypeArguments="x:String"
    		Android="fa-solid-900.ttf#FontAwesome5FreeSolid"
    		iOS="FontAwesome5FreeSolid" />
   
        <OnPlatform 
    		x:Key="FontAwesomeWeb531RIconsFontFamily" 
            x:TypeArguments="x:String"
    		Android="fa-regular-400.ttf#FontAwesome5FreeRegular"
    		iOS="FontAwesome5FreeRegular" />
   
        <OnPlatform 
    		x:Key="FontAwesomeWeb531BFontFamily" 
            x:TypeArguments="x:String"
    		Android="fa-brands-400.ttf#FontAwesome5BrandsRegular"
    		iOS="FontAwesome5BrandsRegular" />
   
        <OnPlatform 
    		x:Key="MaterialIOIconFontFamily" 
            x:TypeArguments="x:String"
    		Android="MaterialIcons-Regular.ttf#MaterialIcons-Regular"
    		iOS="MaterialIcons-Regular" />
   
          </ResourceDictionary>
    </Application.Resources>

Also, when it works on Android, it renders the button two times (flickers) where first it displays the button with the default radius size, and the it renders second time to adjust it to my new radius size.

Hi @wilsonvargas ,

Looking at the source code of your plugin, I think I penciled down where the issue / the enhancement that will be appreciated to support all (free and paid Pro version of ) 3 official FontAwesomeWeb ttf files declared in the info.plist file.
Adding fontawesomeweb.ttf (which is a very old version) in my iOS resource folder did remove the issue. But I don't want to include multiple versions of the FontAwesomeWeb ttf files. I have copied all 3 ttf files as stated in the description the respective resources folders of my in my Android and iOS App projects.

It was working in my android app version because I do have a old copy of the fontawesome file "fontawesome.ttf" in the asset folder, which I did exclude in the iOS version. Not having that file is throwing the error above. I would kindly request to throw a user defined error to indicate missing file. I also plan to remove that ttf file from Android project to eliminate multiple versions and to keep my App size at the optimum level.

I hope you will consider supporting my request.

Thanks
