How to use it

Step 1: Import the FloatingAction component:

import { FloatingAction } from "rn-scrolling-fab";

Second step: define the buttons

const actions = [
  {
     key: "bt_home",
     icon: require("./images/ic_home_white.png"),
  },
  {
     key: "bt_favorite",
     icon: require("./images/ic_favorite_white.png"),
  },
  {
     key: "bt_news",
     icon: require("./images/ic_news_white.png"),
  },
  {
     key: "bt_video",
    icon: require("./images/ic_video_white.png"),
  }
];

or pass icon as component

const actions = [
  {
     key: "UK",
     icon: <Text>🇬🇧</Text>,
  },
  {
     key: "CA",
     icon: <Text>🇨🇦</Text>,
  },
  {
     key: "DE",
     icon: <Text>🇩🇪</Text>,
  },
  {
     key: "USA",
     icon: <Text>🇺🇸</Text>,
  }
];

Third step: use it

<View style={styles.container}>
  <Text style={styles.example}>Floating Action example</Text>
  <FloatingAction
    actions={actions}
    onPressItem={key => {
      console.log(`selected button: ${key}`);
    }}
  />
</View>
