Constructors

EmptyFunctionBodyImpl({required Token semicolon})
Initialize a newly created function body.

Properties

beginToken → Token
Return the first token included in this node's source range.
no setteroverride
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 setteroverride
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
localVariableInfo ↔ LocalVariableInfo?
Additional information about local variables and parameters that are declared within this function body or any enclosing function body. null if resolution has not yet been performed.
getter/setter pairinherited
namedChildEntities → Iterable<ChildEntity>
Return properties (tokens and nodes) of this node, with names, in the order in which these entities should normally appear, not necessary in the order they really are (because of recovery).
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
The token representing the semicolon that marks the end of the function body.
final
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.
override
detachFromParent() → void
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
resolve(ResolverVisitor resolver, DartType? imposedType) → DartType
Dispatch this function body to the resolver, imposing imposedType as the return type context for return statements.
override
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>(bool predicate(AstNode)) → 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
toDartFile([String? path]) → DartFile

Available on AstNode, provided by the AstNodeUtils extension

toDartMethod(DartClass parent) → DartMethod

Available on FunctionBodyImpl, provided by the FunctionBodyImplUtils extension

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.
override

Operators

operator ==(Object other) → bool
The equality operator.
