Hey! @hatpick sorry for replying so late. I'm working on them for DefinitelyTyped, on my fork https://github.com/iRoachie/DefinitelyTyped/tree/react-native-material-kit

The direct path to the types is here - https://github.com/iRoachie/DefinitelyTyped/blob/react-native-material-kit/types/react-native-material-kit/index.d.ts. Still have to add in the Builder stuff

They're done actually! They've been submitted. DefinitelyTyped/DefinitelyTyped#19464
