How to use it

First step: import the component:

import { FloatingAction } from "react-native-floating-action";

Second step: define the buttons

const actions = [
  {
    text: "Accessibility",
    icon: require("./images/ic_accessibility_white.png"),
    name: "bt_accessibility",
    position: 2
  },
  {
    text: "Language",
    icon: require("./images/ic_language_white.png"),
    name: "bt_language",
    position: 1
  },
  {
    text: "Location",
    icon: require("./images/ic_room_white.png"),
    name: "bt_room",
    position: 3
  },
  {
    text: "Video",
    icon: require("./images/ic_videocam_white.png"),
    name: "bt_videocam",
    position: 4
  }
];

Third step: use it

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

Open and hide it programatically

There are some cases where you want to show or hide the component without pressing the main button:

<FloatingAction
  ref={(ref) => { this.floatingAction = ref; }}
  actions={[...]}
  ...
/>

and then:

this.floatingAction.animateButton();
