DartType class - type library

Constructors

DartType()

Properties

aliasArguments → List<DartType>: If this type is an instantiation of a type alias, return the type arguments used for the instantiation. Otherwise return null.
read-only
aliasElement → TypeAliasElement: If this type is an instantiation of a type alias, return it. Otherwise return null.
read-only
displayName → String: Return the name of this type as it should appear when presented to users in contexts such as error messages. [...]
@Deprecated('Use getDisplayString instead'), read-only
element → Element: Return the element representing the declaration of this type, or null if the type has not, or cannot, be associated with an element. The former case will occur if the element model is not yet complete; the latter case will occur if this object represents an undefined type.
read-only
hashCode → int: The hash code for this object. [...]
read-only, inherited
isBottom → bool: Return true if this type represents the bottom type.
read-only
isDartAsyncFuture → bool: Return true if this type represents the type 'Future' defined in the dart:async library.
read-only
isDartAsyncFutureOr → bool: Return true if this type represents the type 'FutureOr' defined in the dart:async library.
read-only
isDartCoreBool → bool: Return true if this type represents the type 'bool' defined in the dart:core library.
read-only
isDartCoreDouble → bool: Return true if this type represents the type 'double' defined in the dart:core library.
read-only
isDartCoreFunction → bool: Return true if this type represents the type 'Function' defined in the dart:core library.
read-only
isDartCoreInt → bool: Return true if this type represents the type 'int' defined in the dart:core library.
read-only
isDartCoreIterable → bool: Returns true if this type represents the type 'Iterable' defined in the dart:core library.
read-only
isDartCoreList → bool: Returns true if this type represents the type 'List' defined in the dart:core library.
read-only
isDartCoreMap → bool: Returns true if this type represents the type 'Map' defined in the dart:core library.
read-only
isDartCoreNull → bool: Return true if this type represents the type 'Null' defined in the dart:core library.
read-only
isDartCoreNum → bool: Return true if this type represents the type 'num' defined in the dart:core library.
read-only
isDartCoreObject → bool: Return true if this type represents the type Object defined in the dart:core library.
read-only
isDartCoreSet → bool: Returns true if this type represents the type 'Set' defined in the dart:core library.
read-only
isDartCoreString → bool: Return true if this type represents the type 'String' defined in the dart:core library.
read-only
isDartCoreSymbol → bool: Returns true if this type represents the type 'Symbol' defined in the dart:core library.
read-only
isDynamic → bool: Return true if this type represents the type 'dynamic'.
read-only
isVoid → bool: Return true if this type represents the type 'void'.
read-only
name → String: Return the name of this type, or null if the type does not have a name, such as when the type represents the type of an unnamed function.
@Deprecated('Check element, or use getDisplayString()'), read-only
nullabilitySuffix → NullabilitySuffix: Return the nullability suffix of this type.
read-only
runtimeType → Type: A representation of the runtime type of the object.
read-only, inherited

Methods

accept<R>(TypeVisitor<R> visitor) → R: Use the given visitor to visit this type.
acceptWithArgument<R, A>(TypeVisitorWithArgument<R, A> visitor, A argument) → R: Use the given visitor to visit this type.
asInstanceOf(ClassElement element) → InterfaceType: Return the canonical interface that this type implements for element, or null if such an interface does not exist. [...]
getDisplayString({bool withNullability}) → String: Return the presentation of this type as it should appear when presented to users in contexts such as error messages. [...]
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed. [...]
inherited
resolveToBound(DartType objectType) → DartType: If this type is a TypeParameterType, returns its bound if it has one, or objectType otherwise. [...]
toString() → String: Returns a string representation of this object.
