How to use custom Appbar.BackAction type in Appbar?

[hbriese]

Currently in Appbar, .type of the children is used to determine what the child is for e.g. AppbarBackAction

Is it possible to override a component's .type so that it can be picked up as the back action?

I can see how this would be done if a different property was used, such as displayName

AppbarBack.displayName = Appbar.BackAction.displayName;

Couldn't find version numbers for the following packages in the issue:

• react-native
• react-native-paper
• react-native-vector-icons

Can you update the issue to include version numbers for those packages? The version numbers must match the format 1.2.3.

The versions mentioned in the issue for the following packages differ from the latest versions on npm:

• react-native-paper (found: 5.0.0-rc.3, latest: 4.12.4)

Can you verify that the issue still exists after upgrading to the latest versions of these packages?

Hey @hbriese, could you please describe or present visually what are you trying to achieve?

Currently it is not possible to render a large appbar header with a menu action in place of the back action, for instance.

Another basic example is using my own wrapper component as the back action. When using these wrappers, the Appbar header component will not correctly identify the wrapper component as the back action and thus will not layout the component in the correct area

Another basic example of this issue with images. To repeat myself, there is no way to get the menu action to be shown in the place of the back action as BackAction.type is used to check and position for the component -- which can't be overridden

Works (small)

<Appbar.Header mode="small">
    <Appbar.Action icon="menu" />
    <Appbar.Content title="Title" />
</Appbar.Header>

Doesn't work (any other mode)

<Appbar.Header mode="large">
    <Appbar.Action icon="menu" />
    <Appbar.Content title="Title" />
</Appbar.Header>

This was incorrectly closed and is still not possible to achieve (using Appbar.Header)
