reassemble method

@override void reassemble()

Called whenever the application is reassembled during debugging, for example during hot reload.

This method should rerun any initialization logic that depends on global state, for example, image loading from asset bundles (since the asset bundle may have changed).

This function will only be called during development. In release builds, the ext.flutter.reassemble hook is not available, and so this code will never execute.

Implementers should not rely on any ordering for hot reload source update, reassemble, and build methods after a hot reload has been initiated. It is possible that a Timer (e.g. an Animation) or a debugging session attached to the isolate could trigger a build with reloaded code before reassemble is called. Code that expects preconditions to be set by reassemble after a hot reload must be resilient to being called out of order, e.g. by fizzling instead of throwing. That said, once reassemble is called, build will be called after it at least once.

• Image, which uses this to reload images.
