ReactNativeHost

This is the main entry-point to create a react-native instance. The ReactNativeHost object exists to configure the instance using ReactInstanceSettings before its loaded, as well as enabling control of when to load the instance.

In the future more lifecycle events will be added to this object to provide better information on when an instance is loaded and unloaded.

Reference

Methods

ReloadInstance()

void ReloadInstance();
