After saving the fonts in my assets folder of my project I linked it by the command react-native link
the links were installed and I cross checked the installation in my android>src>main>assets>fonts
and everything was fine there too and I expected to get the custom font using the styling fontFamily: 'Coda-Heavy'
but I didn't get the required custom font in run
Also please refer to this link I have posted it as an issue in react native:
