To use certain types when writing the `BarCodeScanner` integration, it'll probably be useful to have the types available (not entirely necessary, so this can always be abandoned / revisited at a later point if it takes too much time).
Mainly used the types in the [[ https://github.com/flow-typed/flow-typed/blob/master/definitions/npm/expo-barcode-scanner_v6.x.x/flow_v0.69.0-/expo-barcode-scanner_v6.x.x.js | flow-typed ]] repo as inspiration alongside the actual [[ https://github.com/expo/expo/blob/master/packages/expo-barcode-scanner/src/BarCodeScanner.tsx | typescript ]] file from expo. I did only include the methods in the class that I planned to use, but if it's better to include them all I can do that
Depends on D8770
