 * The first arg is the options object for customization (it can also be null or omitted for default options),
 * The second arg is the callback which sends object: response (more info below in README)
VideoTrimPicker.showVideoTrimPicker(options, (response) => {
  console.log('Response = ', response);

  if (response.didCancel) {
    console.log('User cancelled video picker');
  else if (response.error) {
    console.log('VideoTrimPicker Error: ', response.error);
  else if (response.customButton) {
    console.log('User tapped custom button: ', response.customButton);
  else {
    // You can display the video using either data...
    const source = {uri: 'data:video/mp4;base64,' +, isStatic: true};
    // or a reference to the platform specific asset location
    if (Platform.OS === 'ios') {
      const source = {uri: response.uri.replace('file://', ''), isStatic: true};
    } else {
      const source = {uri: response.uri, isStatic: true};

      myTrimmedVideoSource: source
