Context

Package exposes a context in the form of AvatarContext.

import { Avatar, AvatarContext } from '../.';

function App() {
  const contextValue = React.useMemo(() => ({
    backgrounds: ['#000000', '#DD2C00', '#6200EA', '#3F51B5'], // Any props used by Avatar can be used here.
  }), []);
  return (
    <AvatarContext.Provider>
      <div style={{ display: 'flex' }}>
        <Avatar
          htmlWidth='150px'
          text="Fallback"
          backgrounds={['red']}
          textColor='white'
        />
        <Avatar
          htmlWidth='150px'
          text="AJ"
        />
      </div>
    </AvatarContext.Provider>
  )
}

Values on the Context Provider are overridden by any props that are on the individual component. Context Provider is not compulsory for usage of Avatar component. Read more about Context API on docs.
