React Native component for a user avatar with fallback to colored initials.

A bare-bones user avatar display with support for falling back to using the user's initials on a colored background as the avatar.

Installation

npm install --save react-native-user-avatar or yarn add react-native-user-avatar

Usage

<UserAvatar size="100" name="Avishay Bar" />
  <UserAvatar size="100" name="Avishay Bar" src="https://dummyimage.com/100x100/000/fff" />
  <UserAvatar size="50" name="John Doe" colors={['#ccc', '#fafafa', '#ccaabb']}/>
  <UserAvatar size="50" name="John Doe" />
  <UserAvatar size="50" name="Jane Doe" color="#000" />

User-defined Image-Component

It is also possible to use another Image-Component than the built-in <Image> . 

<UserAvatar size="50" name="John Doe" component={CachedImage} />

The fallback avatar's color may be set by passing in the color prop, or you can customize the range of colors

used by passing in an array of colors . The component uses a simple calculation to consistently use the same

color for the same user's name every time.
