* Fixing issue with notification showing as a white square for application icons that do not follow the notification icon Standard. Should be a non breaking change as the fall back should pull the application icon if it's not defined
* Not sure how long this error has been here but we are importing the wrong thing. We should be importing NonNull as importing Nullable causes a build error. The RN 60 flavor of the file is importing the NonNull
* Updating documentation for the Icon
* Fixing image name and updating documentation
* Update installation.md
Forgot one more place to update the file name
