ScopeAutoDependencies<T extends ScopeAutoDependencies<T, C> , C extends Object?> class
abstract
base
Scope
A container that builds its dependency tree and initializes it for you.
T is the class being declared — final class AppDeps extends ScopeAutoDependencies<AppDeps, BuildContext>. It is what init hands the
scope on success, so it is what the subtree gets from Scope.of, and the
bound is what keeps the two the same thing: naming another container there
used to compile and then fail at the end of a successful initialization,
with the whole tree already built and nothing left to release it.
C is what buildDependencies is given — a BuildContext when the tree
reads scopes above it, void when it needs nothing.

Methods
-
asStream<
P extends Object> () → Stream< ScopeInitState< P, T> > -
Available on T, provided by the ScopeDependenciesExtension extension
Converts the dependencies into a stream emitting a ScopeReady state. -
buildDependencies(
C context) → ScopeDependency - Build the queue of dependencies.
-
concurrent(
String name, Iterable< ScopeDependency> dependencies) → ScopeDependency - A group whose children are initialized in parallel.
-
controllerDep<
S extends ScopeController> (String name, S create()) → ScopeDependency - A single dependency backed by a ScopeController.
-
dep(
String name, FutureOr< void> init(ScopeDependencyHandle dep)) → ScopeDependency -
A single dependency called
name. -
dispose(
) → Future< void> -
Disposes of the dependencies, releasing any resources they hold.
override
-
flattenDependencies(
) → Iterable< ScopeDependencyInfo> - Walks the tree depth-first.
-
flattenDependenciesWithErrors(
) → Iterable< ScopeDependencyInfo> - The entries that hold a real error.
-
init(
C context) → Stream< ScopeInitState< ScopeAutoDependenciesProgress, T> > - Initialize the scope dependencies.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onUnmount(
) → void -
Lets go of whatever cannot wait for dispose.
override
-
sequential(
String name, Iterable< ScopeDependency> dependencies) → ScopeDependency - A group whose children are initialized one after another.
-
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
