Review Comment:
   ```suggestion
           const isAdaptiveIcon = background && foreground;
           const isMonochromeIcon = monochrome && isAdaptiveIcon;
           if (!isMonochromeIcon || !isAdaptiveIcon) {
   ```
   Will something like this work for readability? 
   
   Might need to test to confirm what I written.
   
   - Monochrome must also have a background and foreground.
   - Adaptive Icon minimum support does not require the monochrome definition.
   - Standard Icon is used when not monochrome or minimum adaptive icon.
   
   Ideally we hope all three is defined so end users can have a nice user 
experience when themed is enabled, but its possbile posible for the app 
developers to not have yet created monochrome assets and can still fallback to 
the adaptive icons they have now.
