Classes

AST

An abstraction representing a component of a parsed Dart expression.

AstTransformer

AstVisitor<R, C>

ASTWithSource

Wraps an AST with source and location information.

Binary

Represents a binary expression, i.e. left operator right.

BindingPipe

A method call that has been interpreted as a specialized "pipe" invocation.

Conditional

A ternary or where condition will either pick trueExpr or falseExpr.

EmptyExpr

A placeholder expression used when otherwise no expression is parsed/found.

FunctionCall

Similar to MethodCall, but target is callable.

IfNull

Represents the "if null" (??) operator.

ImplicitReceiver

The "root" expression (the context in which the expression is evaluated).

Interpolation

Represents converting a result or multiple results explicitly to a String.

KeyedRead

Similar to PropertyRead, but uses bracket operator [] to refer to key.

KeyedWrite

Similar to PropertyWrite using bracket operator []= to refer to key.

LiteralPrimitive

Represents a primitive value (either number, String, bool, or null).

MethodCall

A call to a method.

NamedExpr

Represents a "named" expression, i.e. in the format of name: expression.

PostfixNotNull

Coerces T? to T, throwing if null, i.e. var!.

PrefixNot

A unary prefixed "not" expression, i.e. !expr.

PropertyRead

Reads a property (getter or field) name from receiver.

PropertyWrite

Writes a property (setter or field) name to receiver.

RecursiveAstVisitor<C>

SafeMethodCall

Similar to MethodCall, but only if the receiver is non-null.

SafePropertyRead

Similar to PropertyRead, but avoids NPEs by using ?. instead of ..

StaticRead

A reference to a "static" variable or identifier represented by id.

VariableRead

A reference to a local variable name.
