FuchsiaViewConnection class

*<Null safety>*

Defines a thin wrapper around FuchsiaViewController.

Its primary purpose is to hold on to ViewHolderToken for the lifetime of the view controller, since FuchsiaViewController is agnostic to all Fuchsia data types. (Eventually, FuchsiaView and FuchsiaViewController will be moved to Flutter framework, which cannot have Fuchsia data types.)

pointerInjector → PointerInjector

Returns the PointerInjector instance used by this connection.
@visibleForTesting, read-only

runtimeType → Type

A representation of the runtime type of the object.
read-only, inherited

startupContext → StartupContext

Returns the StartupContext used to connect to required services.
@visibleForTesting, read-only
