Properties

beginToken Token
Return the first token included in this node's source range.
no setterinherited
childEntities Iterable<SyntacticEntity>
Return 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
end int
Return the offset of the character immediately following the last character of this node's source range.
no setterinherited
endToken Token
Return the last token included in this node's source range.
no setterinherited
expression Expression
Return the expression representing the body of the function.
no setter
functionDefinition Token
Return the token introducing the expression that represents the body of the function.
no setter
hashCode int
The hash code for this object.
no setterinherited
isAsynchronous bool
Return true if this function body is asynchronous.
no setterinherited
isGenerator bool
Return true if this function body is a generator.
no setterinherited
isSynchronous bool
Return true if this function body is synchronous.
no setterinherited
isSynthetic bool
Return true if this node is a synthetic node.
no setterinherited
keyword Token?
Return the token representing the 'async' or 'sync' keyword, or null if there is no such keyword.
no setterinherited
length int
Return the number of characters in the syntactic entity's source range.
no setterinherited
offset int
Return the offset from the beginning of the file to the first character in the syntactic entity.
no setterinherited
parent AstNode?
Return this node's parent node, or null if this node is the root of an AST structure.
no setterinherited
root AstNode
Return the node at the root of this node's AST structure.
no setterinherited
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
semicolon Token?
Return the semicolon terminating the statement.
no setter
star Token?
Return the star following the 'async' or 'sync' keyword, or null if there is no star.
no setterinherited

Methods

accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node.
inherited
findPrevious(Token target) Token?
Return the token before target or null if it cannot be found.
inherited
getProperty<E>(String name) → E?
Return the value of the property with the given name, or null if this node does not have a property with the given name.
inherited
isPotentiallyMutatedInClosure(VariableElement variable) bool
If variable is a local variable or parameter declared anywhere within the top level function or method containing this FunctionBody, return a boolean indicating whether variable is potentially mutated within a local function other than the function in which it is declared.
inherited
isPotentiallyMutatedInScope(VariableElement variable) bool
If variable is a local variable or parameter declared anywhere within the top level function or method containing this FunctionBody, return a boolean indicating whether variable is potentially mutated within the scope of its declaration.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setProperty(String name, Object? value) → void
Set the value of the property with the given name to the given value. If the value is null, the property will effectively be removed.
inherited
thisOrAncestorMatching<E extends AstNode>(Predicate<AstNode> predicate) → E?
Return either this node or the most immediate ancestor of this node for which the predicate returns true, or null if there is no such node.
inherited
thisOrAncestorOfType<E extends AstNode>() → E?
Return either this node or the most immediate ancestor of this node that has the given type, or null if there is no such node.
inherited
toSource() String
Return a textual description of this node in a form approximating valid source.
inherited
toString() String
A string representation of this object.
inherited
visitChildren(AstVisitor visitor) → void
Use the given visitor to visit all of the children of this node.
