custom font weight not working about react-native-paper HOT 3 OPEN

Hey there, I had the same problem some weeks ago, installing the individual font families fixed this for me. I also had to remove 'fontWeight' property from all of my fonts' config. Example code below:

export const fonts {
  titleLarge: {
    fontFamily: 'RedHatDisplay-ExtraBold',
    fontSize: 34,
    letterSpacing: 0.37,
    lineHeight: 41,
  },
  bodyMedium: {
    fontFamily: 'RedHatDisplay-Medium',
    fontSize: 16,
    letterSpacing: 0.36,
    lineHeight: 34,
  },
  bodySmall: {
    fontFamily: 'RedHatDisplay-Regular',
    fontSize: 14
    letterSpacing: 0.35,
    lineHeight: 46,
  },
...
};

This way I set the fontWeight using the specific fontFamily I installed. I also tried using some variable fonts but it seems those aren't compatible yet.

So I'd try removing fontWeight from your fonts' config, and setting it just with fontFamily.

Here's another useful issue you could check: facebook/react-native#42116

Only other thing is I noticed you're importing Text from "react-native". I don't know if you're also importing it that way in other modules but it should be imported from "react-native-paper". That way it'll properly use the fonts provided by your theme.
