scope library

Classes

GlobalScope: Experimental. Use with caution as the api is likely to change. This is intended as a replacement for Get It but with a consistent api to Scope as well as being sensitive to ScopeKeys in Scope. Values injected into a GlobalScope by injecting the same key into a Scope.
Scope: Creates a Scope providing dependency injection to your call stack.
ScopeKey<T>: The only purpose of ScopeKeys is to be globally unique so that they can be used to uniquely identify injected values. ScopeKeys are opaque – you are not supposed to read any other information from them except t heir identity.

hasScopeKey<T>(ScopeKey<T> key) → bool: Returns true if key is contained within the current Scope or an ancestor Scope
isNullable<T>() → bool: Returns true if T was declared as a nullable type (e.g. String?)
isWithinScope() → bool: Returns true if the caller is running within a Scope
use<T>(ScopeKey<T> key, {T withDefault()?}) → T: Returns the value injected for key

CircularDependencyException<T>: Thrown by use when called inside a Scope.single or Scope.sequence callback and the keys factories try to mutually inject each other.
DuplicateDependencyException<T>: Thrown if an attempt is made to inject the same ScopeKey twice into the same Scope.
MissingDependencyException<T>: Thrown by use when no value has been registered in the Scope for _key and it has no default value.
