Using Navigate in Class Component React Native

If you are working with React Native and building an app which requires navigating between different screens, you need to know how to navigate in class component. In React Native, you can use the NavigationActions and StackActions modules to navigate between screens.

Using NavigationActions

The NavigationActions module lets you navigate between screens by dispatching an action. Here is an example of how to use it:

import { NavigationActions } from 'react-navigation';

class HomeScreen extends React.Component {
  goToScreen = () => {
    const navigateAction = NavigationActions.navigate({
      routeName: 'Screen2',
      params: { param: 'Hello' },
      action: NavigationActions.navigate({ routeName: 'Screen3' }),
    });
    this.props.navigation.dispatch(navigateAction);
  };
}
    

In this example, we define a function called goToScreen which dispatches a navigate action with the route name of "Screen2" and a parameter called "param" with the value "Hello". It also dispatches another navigate action to go to "Screen3".

Using StackActions

The StackActions module lets you manipulate the navigation stack. Here is an example of how to use it:

import { StackActions } from 'react-navigation';

class HomeScreen extends React.Component {
  goToScreen = () => {
    const pushAction = StackActions.push({
      routeName: 'Screen2',
      params: { param: 'Hello' },
    });
    this.props.navigation.dispatch(pushAction);
  };
}
    

In this example, we define a function called goToScreen which dispatches a push action with the route name of "Screen2" and a parameter called "param" with the value "Hello". This adds a new screen to the stack and navigates to it.

Conclusion

These are the two main ways to navigate between screens in class components in React Native. You can use either of them depending on your specific needs. Remember to import the necessary modules and dispatch the actions to navigate.
