Service<T> class

A simple utility class that encapsulates a Create and a Dispose function and generates a Provider in order to make the object created with the Create function available in the widget tree.

Just like Providers, the Create function is called lazily by default. If the Service needs to be initialized greedly, the lazy parameter can be used:

AppGadget(
 services: [
    Service(create: (_) => MyCustomService(), lazy: false),
 ]
 child: MyChildWidget()
);

A list of services can be specified when creating a new AppGadget widget:

AppGadget(
 services: [
    Service(create: (_) => MyCustomObject()),
    Service(create: (_) => MyOtherCustomObject()),
 ]
 child: MyChildWidget()
);
