React Navigation - navigating to another tab and reset stack : <p>I'm trying to route from one StackNavigator to another, both of which are inside a TabNavigator. I'm currently able to get there by simply doing:</p>

<pre><code>this.props.navigation.navigate('Screen3')
</code></pre>

<p>But I also want to reset that tab when I go to it. Here is how my app navigators are generally set up:</p>

<pre><code>- Main (StackNavigator)
  - LoginScreen
  - MainTabs (TabNavigator)
    - Tab1 (StackNavigator)
      - Screen1
      - Screen2
    - Tab2 (StackNavigator)
      - Screen3
      - Screen4
</code></pre>

<p>How could I navigate to <code>Screen3</code> but also reset the StackNavigator <code>Tab2</code>?</p>

<p>I've also tried doing this, to no avail:</p>

<pre><code>let resetAction = NavigationActions.reset({
  index: 0,
  key: 'Tab2',
  actions: [
    NavigationActions.navigate({ routeName: 'Screen3' })
  ],
});

this.props.navigation.dispatch(resetAction);
</code></pre>
