Constructors
- ExpressionFunctionBodyImpl({required Token? keyword, required Token? star, required Token functionDefinition, required ExpressionImpl expression, required Token? semicolon})
-
Initialize a newly created function body consisting of a block of
statements. The keyword can be
null
if the function body is not an async 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
- expression ↔ ExpressionImpl
-
Return the expression representing the body of the function.
getter/setter pairoverride-getter
- functionDefinition → Token
-
The token introducing the expression that represents the body of the
function.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- isAsynchronous → bool
-
Return
true
if this function body is asynchronous.no setteroverride - isGenerator → bool
-
Return
true
if this function body is a generator.no setteroverride - isSynchronous → bool
-
Return
true
if this function body is synchronous.no setteroverride - isSynthetic → bool
-
Return
true
if this node is a synthetic node.no setterinherited - keyword → Token?
-
The token representing the 'async' keyword, or
null
if there is no such keyword.final - 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 semicolon terminating the statement.
final
- star → Token?
-
The star optionally following the 'async' or 'sync' keyword, or
null
if there is wither no such keyword or no star.final
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
ornull
if it cannot be found.inherited -
getProperty<
E> (String name) → E? -
Return the value of the property with the given
name
, ornull
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 whethervariable
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 whethervariable
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 forreturn
statements.override -
setProperty(
String name, Object? value) → void -
Set the value of the property with the given
name
to the givenvalue
. If the value isnull
, 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
returnstrue
, ornull
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.override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
