ConfigurableScope class abstract

ConfigurableScope is a draft of scope that can be configured with scope.expose and scope.addDispose methods, it is often used during scope creation.

Normal Scope can not been configured after creation.

Not Feasible:

final Scope rootScope = await Scope.root([]);

final repository = Repository();
rootScope.expose<Repository>( // Error: 'scope.expose' isn't defined
  expose: () => repository
);

It's recommended to configure scope during creation via ConfigurableScope.

Feasible:

final Scope rootScope = await Scope.root([
  Configurable((ConfigurableScope scope) {
    final repository = Repository();
    scope.expose<Repository>( // works as expected
      expose: () => repository
    );
  })
]);

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

addDisposable(Disposable disposable) → void

add a disposable to current sink.

inherited

addDisposables(List<Disposable> disposables) → void

add a list of disposable to current sink.

inherited

dispose() → void

As opposite to scope.push, scope can also be disposed/popped. We can register dispose logic, that will run when scope been disposed:

inherited

expose<T>({Object? name, required Getter<T> expose}) → void

Use scope.expose<T>(...) to expose instance within current scope, this instance can be resolved later:

inherited

getOrNull<T>({Object? name}) → T?

Use scope.getOrNull<T>(...) to safely resolve instance. This method will return null when instance is not exposed:

inherited

has<T>({Object? name}) → bool

Use scope.has<T>(...) to check if instance has been exposed:

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

push(List<Configurable> configure) → FutureOr<Scope>

Use scope.push(...) to create a new child scope. Child scope inherited getters from parent:

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
