A quick solution for anyone dealing with Cannot read property 'style' of undefined

[michaelkowalski]

Just remove the library:

yarn remove react-native-material-textfield

And then add my fork:

yarn add michaelkowalski/react-native-material-textfield

I know other poeple have posted patch files and alternative libraries but personally I'm used to this one (especially for simple projects that don't need bigger component libraries) and this is the quickest fix I came up with without any additional steps.
