Methods

canAcceptValue(dynamic nativeValue) → bool
Checks if type can accept the given native value.
inherited
createValue(dynamic nativeValue) → TypedValue
Creates a TupleValue from native Dart list.
override
createValueOrThrow<T extends TypedValue>(dynamic nativeValue) → T

Available on AbiType, provided by the AbiTypeOrThrowExtensions extension

Creates a TypedValue from native value and ensures it matches expected type.
equals(AbiType other) → bool
Checks type equality based on fully qualified names.
inherited

inherited
isAssignableFrom(AbiType other) → bool

inherited
isValidValue(dynamic value) → bool

Available on AbiType, provided by the AbiTypeExtensions extension

Checks if the value is valid for this type.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
requireType<T extends AbiType>(String message) → T

Available on AbiType, provided by the AbiTypeValidationExtensions extension

Ensures this type is an instance of T, throwing with a custom message if not.
toMap() → Map<String, dynamic>
inherited
toString() → String
