There was a problem hiding this comment.
Given the following dart code:
Foo()..value = 1;This is what the generated ast results in
Foo()..value = 1; (ExpressionStatement)
Foo()..value = 1 (CascadeExpression)
Foo() (MethodInvocation)
Foo (SimpleIdentifier)
() (ArgumentList)
..value = 1 (AssignmentExpression) <----- (extends from CompoundAssignmentExpression)
..value (PropertyAccess)
value (SimpleIdentifier)
1 (IntegerLiteral)
Given the above code, value (SimpleIdentifier) is the case that makes it to this conditional. If we refer to the ast, the parent of this element is PropertyAccess, not CompoundAssignmentExpression, which tells us this expression can occur at multiple depths, not just the parent
We can solve this by just searching for the closest node of the specific type, and treat that as the assignment expression we care about
