"Error: Binding has not yet been initialized " when running on device "chrome"

[rwbr]

When you try to run the example in a web browser flutter run -d chrome, the following exception is getting thrown:

❯ flutter run -d chrome                                                                                      [16:18:18]

Flutter Web Bootstrap: Programmatic
Error: Binding has not yet been initialized.
The "instance" getter on the ServicesBinding binding mixin is only available once that binding has been initialized.
Typically, this is done by calling "WidgetsFlutterBinding.ensureInitialized()" or "runApp()" (the latter calls the
former). Typically this call is done in the "void main()" method. The "ensureInitialized" method is idempotent; calling
it multiple times is not harmful. After calling that method, the "instance" getter will return the binding.
In a test, one can call "TestWidgetsFlutterBinding.ensureInitialized()" as the first line in the test's "main()" method
to initialize the binding.
If ServicesBinding is a custom binding mixin, there must also be a custom binding class, like WidgetsFlutterBinding, but
that mixes in the selected binding, and that is the class that must be constructed before using the "instance" getter.

It leads the application to crash when executing

DtmfPlugin.registerWith(registrar);

in file generated_plugin_registrant.
