Constructors
Properties
- beginToken → Token

Return the cases that can be selected by the expression.
no setter
-
childEntities
→ Iterable<
SyntacticEntity> -

Return the expression used to determine which of the switch cases will
be selected.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- inConstantContext → bool
-
An expression e is said to occur in a constant context,
no setterinherited
- isAssignable → bool
-
Return
true
if this expression is syntactically valid for the LHS of an AssignmentExpression.no setterinherited - isSynthetic → bool

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 - precedence → Precedence
-
Return the precedence of this expression.
no setterinherited
- rightBracket → Token
-
Return the right curly bracket.
no setter

no setter
- 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
- staticParameterElement → ParameterElement?
-
If this expression is an argument to an invocation, and the AST structure
has been resolved, and the function being invoked is known based on static
type information, and this expression corresponds to one of the parameters
of the function being invoked, then return the parameter element
representing the parameter to which the value of this expression will be
bound. Otherwise, return
null
.no setterinherited - staticType → DartType?
-
Return the static type of this expression, or
null
if the AST structure has not been resolved.no setterinherited - switchKeyword → Token
-
Return the token representing the 'switch' keyword.
no setter
- unParenthesized → Expression
-
If this expression is a parenthesized expression, return the result of
unwrapping the expression inside the parentheses. Otherwise, return this
expression.
