  this.props.copilotEvents.on('stepChange', this.handleStepChange);

  // TODO: Start tutorial --> NO thing happen. Even if invole props.start fron a button's click even, still not show tutorial, nothing happen
  this.props.start();
}

handleStepChange = (step) => {
  console.log(`hcmus 3: Current step is: ${step.name}`);
}


render() {
    return (

      <StyleProvider style={getTheme(platform)}>
      <Root>
      {/* <CopilotStep text="This is a hello world example!" order={1} name="hello">
          <CopilotText onPress={() => this.handleStartButtonPress()}>Hello world!</CopilotText>
        </CopilotStep> */}
      <Container>
      <CustomHeader title='Dashboard'/>

      // TODO: Here is place define step
      <CopilotStep text="This is a hello_222 world example!" order={2} name="hello_222">
          <CopilotText onPress={() => this.handleStartButtonPress()}>Hello world 2222!</CopilotText>
      </CopilotStep>
     
     ...
     ... 

      </Container>
      {this.state.loading &&
        <View style={globalStyles.loading}>
          <Spinner color='white' />
        </View>
      }
      </Root>
      </StyleProvider>
    );
  }
}

// TODO: export copilot
export default copilot({
  animated: true, // Can be true or false
  overlay: 'svg', // Can be either view or svg
})(Annoucement);

Expected behavior/code
The tutorial should be shown when invoking the this.props.start()

Environment

• Device: Nexus 5X - Android SDK Simulator
• OS: Android 9
• react-native-copilot: ^2.4.1
• react-native: 0.55.4
• react-native-svg: ^6.3.1
• react-navigation: ^2.11.2

Possible Solution
It could be related to react-navigation, I think, but not sure,

Additional context/Screenshots

Start by reproducing the issue in the Annoucement component with the listed React Native, react-native-copilot, and react-navigation versions. Inspect componentDidMount, the this.props.start() call, and the copilot(...) export; done means the tutorial appears when start() is invoked and the stepChange event still works.
