@xxsnakerxx thanks for your PR! Would it however be possible to make the StyleSheet match configurable rather than an includes match?

[xxsnakerxx]

Great idea! We can add a setting for the plugin, we can name it something like react-native/style-sheet-object-names. By default, it will be ['StyleSheet'] and a user can override this in the config

...
settings: {
    'react-native/style-sheet-object-names': ['EStyleSheet', 'OtherStyleSheet']
}
...

Do you agree?

@xxsnakerxx yeah looks good, very nice :D I'll create a release this weekend!
