When building my react-native app with expo and browsing it using Firefox on my machine, I get the following warnings:
Warning: React does not recognize the `duotoneColor` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `duotonecolor` instead. If you accidentally passed it from a parent component, remove it from the DOM element.
Warning: React does not recognize the `duotoneOpacity` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `duotoneopacity` instead. If you accidentally passed it from a parent component, remove it from the DOM element.
I get these errors for phosphor-react-native v2.2.2 and v2.2.1 (v2.1.0 fails with a different set of errors).
Thank you for the nice library!
