InterpreterVisitor class

Main visitor that walks the AST and interprets the code. Uses a two-pass approach (DeclarationVisitor first).

Inheritance

• Object
• GeneralizingAstVisitor<Object?>
• InterpreterVisitor

Available extensions

• InterpreterVisitorExtension

Constructors

InterpreterVisitor({required Environment globalEnvironment, required ModuleLoader moduleLoader, Uri? initiallibrary})

Properties

currentAsyncState ↔ AsyncExecutionState?

getter/setter pair

currentFunction ↔ InterpretedFunction?

getter/setter pair

environment ↔ Environment

getter/setter pair

globalEnvironment → Environment

final

hashCode → int

The hash code for this object.

no setter, inherited

isLazySyncGeneratorContext ↔ bool

For lazy sync* generators: when true, yield throws SyncYieldSuspension to pause execution and bubble up through the call stack.

getter/setter pair

moduleLoader → ModuleLoader

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

syncGeneratorValues ↔ List<Object?>?

For sync* generators: the list to collect yielded values into. When non-null, yield statements add directly to this list.

getter/setter pair

Methods

toBridgedInstance(Object? nativeObject, {String? methodName}) → (BridgedInstance<Object>?, bool)

Available on InterpreterVisitor, provided by the InterpreterVisitorExtension extension
