launch options
the examples demonstrate running flutter using the default launch settings.
in order to customize your flutter runtime,
you can also specify the dart entrypoint, library, and route.

dart entrypoint
calling run on a FlutterEngine, by default,
runs the main() dart function
of your lib/main.dart file.
you can also run a different entrypoint function by using
runWithEntrypoint with an NSString specifying
a different dart function.
info note
dart entrypoint functions other than main()
must be annotated with the following in order to
not be tree-shaken away when compiling:

dart library
in addition to specifying a dart function, you can specify an entrypoint
function in a specific file.
for instance the following runs myOtherEntrypoint()
in lib/other_file.dart instead of main() in lib/main.dart:
<topic_end>
<topic_start>
route
starting in flutter version 1.22, an initial route can be set for your flutter
