Example of how to use

To load a font dynamically, you must first have a base64 string of your font file (TTF or OTF):

import { loadFont, loadFonts } from 'react-native-dynamic-font';

...
/* Load a single font */
loadFont('nameOfFont', base64FontString, 'ttf').then(function(name) {
	console.log('Loaded font successfully. Font name is: ', name);
});

/* Load a list of fonts */
loadFonts([{name: 'nameOfFont', data: base64FontString, type: 'ttf'}]).then(function(names) {
	console.log('Loaded all fonts successfully. Font names are: ', names);
});

...

Font loading using file path

You can download font file to file system and then load it to app without sending base64 to bridge.

import {loadFontFromFile} from 'react-native-dynamic-font';
import RNFetchBlob from 'rn-fetch-blob'

const fontFilePath = RNFetchBlob.fs.dirs.DocumentDir + "fonts/roboto.ttf";

loadFontFromFile("Roboto",  fontFilePath)
   .then(function(name) {
   	    console.log('Loaded font successfully. Font name is: ', name);
   });
