Disable back button in react navigation

Solution 1:

1) To make the back button disappear in react-navigation v2 or newer:

v2-v4:

navigationOptions:  {
    title: 'MyScreen',
    headerLeft: null
}

v5:

{     
    navigationOptions:  {
    title: 'MyScreen',
    headerLeft: ()=> null, // Note: using just `null` instead of a function should also work but could trigger a TS error
}

2) If you want to clean navigation stack:

Assuming you are on the screen from which you want to navigate from:

If you are using react-navigation version v5 or newer you can use navigation.reset or CommonActions.reset:

 // Replace current navigation state with a new one,
 // index value will be the current active route:

navigation.reset({
  index: 0,
  routes: [{ name: 'Profile' }],
});

Source and more info here: https://reactnavigation.org/docs/navigation-prop/#reset

Or:

navigation.dispatch(
  CommonActions.reset({
    index: 1,
    routes: [
      { name: 'Home' },
      {
        name: 'Profile',
        params: { user: 'jane' },
      },
    ],
  })
);

Source and more info here: https://reactnavigation.org/docs/navigation-actions/#reset

For older versions of react-navigation:

v2-v4 use StackActions.reset(...)

import { StackActions, NavigationActions } from 'react-navigation';

const resetAction = StackActions.reset({
  index: 0, // <-- currect active route from actions array
  actions: [
    NavigationActions.navigate({ routeName: 'myRouteWithDisabledBackFunctionality' }),
  ],
});

this.props.navigation.dispatch(resetAction);

v1 use NavigationActions.reset

3) For android you will also have to disable the hardware back button using the BackHandler:

http://reactnative.dev/docs/backhandler.html

or if you want to use hooks:

https://github.com/react-native-community/hooks#usebackhandler

otherwise the app will close at android hardware back button press if navigation stack is empty.

Solution 2:

Have you considered using this.props.navigation.replace( "HomeScreen" ) instead of this.props.navigation.navigate( "HomeScreen" ).

This way you are not adding anything to the stack. so HomeScreen won't wave anything to go back to if back button pressed in Android or screen swiped to the right in IOS.

More informations check the Documentation. And of course you can hide the back button by setting headerLeft: null in navigationOptions

Solution 3:

We need to set false to the gesturesEnabled along with headerLeft to null. Because we can navigate back by swiping the screen as well.

navigationOptions:  {
   title: 'Title',
   headerLeft: null,
   gestureEnabled: false,
}

Solution 4:

You can hide the back button using left:null, but for android devices it's still able to go back when the user presses the back button. You need to reset the navigation state and hide the button with left:null

Here are the docs for resetting navigation state:
https://reactnavigation.org/docs/navigation-actions#reset

This solution works for react-navigator 1.0.0-beta.7, however left:null no longer works for the latest version.

Solution 5:

using the BackHandler from react native worked for me. Just include this line in your ComponentWillMount:

BackHandler.addEventListener('hardwareBackPress', function() {return true})

it will disable back button on android device.
