fix: context is never null

[cruzach]

Description

fixes an error when building for android on different kotlin versions / lint setups

I have changed the project's gradle setup to match the Example/ in this repo, but still getting the error... but even though this could be kotlin version issue, it seems to me that context can't be null here anyways, so figured I'd open a PR for review 🤷

Changes

context is never null according to the constructor, so I just changed one instance of Context? to Context
