Default JS Dispatcher for React Native is wrong

[Legion2]

As part of ecc68f1 the Default dispatcher for React Native was set to NodeDispatcher. However, there is no process.nextTick in React Native environments. There is only a fake process.env object but nothing else. As a result the Default dispatcher does not work in React Native.

So I tested the other dispatchers. In React Native environments the SetTimeoutDispatcher works well. If React Native is executed with a Debugger (Chrome) the JS code is executed in a Chrome worker. In this mode SetTimeoutDispatcher and window.asCoroutineDispatcher() can be used as dispatchers, NodeDispatcher does not work.

To resolve this issue, createDefaultDispatcher must be adapted, so it properly detects the fake process object without the nextTick function.

If needed I can provide a PR and test changes.

Thanks for the detailed explanation! The PR is very welcome

Wooow, when will this change be released!?

Is there any current work around?

[Legion2]

you can create your own dispatcher based on the one in the fix and then use it explicitly when launching coroutines

[andylamax]

Already did. Just thought maybe there would be one which would require me not to state explicitly which dispatcher
