ConstructorDeclaration class abstract final

A constructor declaration.

constructorDeclaration ::= constructorSignature FunctionBody? | constructorName formalParameterList ':' 'this' ('.' SimpleIdentifier)? arguments

constructorSignature ::= 'external'? constructorName formalParameterList initializerList? | 'external'? 'factory' factoryName formalParameterList initializerList? | 'external'? 'const' constructorName formalParameterList initializerList?

constructorName ::= SimpleIdentifier ('.' name)?

factoryName ::= Identifier ('.' SimpleIdentifier)?

initializerList ::= ':' ConstructorInitializer (',' ConstructorInitializer)*
