TypeError: Cannot use 'in' operator to search for 'method' in 9

I had this code working in version 5.0.1:

<WebView
    source={require('page.html')}
/>

and in 5.7.0, it crashes on Android (still works on iOS):

I’m assuming that it happens because of this line, introduced by the js to ts rewrite (this commit).

It seems the author of this rewrite forgot to handle using require in the source prop.

I’m currently bypassing the problem this way:

<WebView
    source={{uri: Image.resolveAssetSource(require('page.html')).uri}}
/>

This should be fixed though and a test should be added to ensure it doesn’t happen again.

@Titozzz Because the documentation cannot change?

Do you really expect people to read the entire documentation and notice the api changes at every update? No, that’s why you should not drop features silently, that’s why properly managed projects have a changelog file, but there is none in this repository.

@vmarquet Docs never specified you syntax should have worked which is why you encountered that issue. See (docs)[https://github.com/react-native-community/react-native-webview/blob/master/docs/Reference.md#source].

This should be fixed though and a test should be added to ensure it doesn’t happen again.

If you think changes need to be done in a repository, please submit a pull request, since you already spent time to track the bug, it’s even more enjoyable.
