FormalParameterList class abstract final

The formal parameter list of a method declaration, function declaration, or function type alias.

Required positional parameters are represented by requiredPositionalFormalParameters. Optional positional or named parameters are represented by delimitedFormalParameters, whose DelimitedFormalParameters.isNamed getter identifies the form of the delimited group.

The compatibility parameters getter projects both structural positions as a single, fixed-length list.

formalParameterList ::= '(' ')' | '(' normalFormalParameters (',' optionalFormalParameters)? ')' | '(' optionalFormalParameters ')'

normalFormalParameters ::= FormalParameter (',' FormalParameter)*

optionalFormalParameters ::= optionalPositionalFormalParameters | namedFormalParameters

optionalPositionalFormalParameters ::= '[' FormalParameter (',' FormalParameter)* ']'

namedFormalParameters ::= '{' FormalParameter (',' FormalParameter)* '}'

Properties

beginToken → Token
The first token included in this node's source range.
no setterinherited
childEntities → Iterable<SyntacticEntity>
An iterator that can be used to iterate through all the entities (either AST nodes or tokens) that make up the contents of this node, including doc comments but excluding other comments.
no setterinherited
childEntities2 → Iterable<SyntacticEntity>
An iterator that can be used to iterate through all the entities (either AST nodes or tokens) that make up the contents of this node, including doc comments but excluding other comments.
no setterinherited
delimitedFormalParameters → DelimitedFormalParameters?
The optional positional or named formal parameters, or null if there are no delimited formal parameters.
no setter
end → int
The offset of the character immediately following the last character of this node's source range.
no setterinherited
endToken → Token
The last token included in this node's source range.
no setterinherited

The hash code for this object.
no setterinherited
isSynthetic → bool
Whether this node is a synthetic node.
no setterinherited
leftDelimiter → Token?
The left square bracket ('[') or left curly brace ('{') introducing the optional or named parameters, or null if there are neither optional nor named parameters.
no setter
leftParenthesis → Token
The left parenthesis.
no setter
length → int

no setter
parameters → NodeList<FormalParameter>
The parameters associated with the method.
no setter
parent → AstNode?

no setterinherited
requiredPositionalFormalParameters → NodeList<FormalParameter>
The required positional formal parameters at the start of this list.
no setter
rightDelimiter → Token?
The right square bracket (']') or right curly brace ('}') terminating the optional or named parameters, or null if there are neither optional nor named parameters.
no setter
rightParenthesis → Token
The right parenthesis.
no setter
root → AstNode
The node at the root of this node's AST structure.
