type 'Keyword' is not a subtype of type 'String' in type cast

[Noobware1]

this error is occuring when i try access a decoded json value and cast it to a list type in this line
var source = decrypted['source'] as List

if i remove this line from the code it works fine but the error even occurs when
using .map without casting
using list generate without casting
and i if try do a for in loop and a simple for loop without casting it throws this error

dart_eval runtime exception: type 'bool' is not a subtype of type '$Instance' in type cast

#2      EvalStaticFunctionPtr.call (package:dart_eval/src/eval/runtime/function.dart:78:13)

this is what the decoded json looks like

{$"source": Instance of '$List<$Value?>', $"source_bk": Instance of '$List<$Value?>', $"track": Instance of '$Map<$Value?, $Value?>', $"advertising": Instance of '$List<$Value?>', $"linkiframe": $"https://awish.pro/e/dlvko8lituey"}

@ethanblake4 you can closed this issue if want
found out that && operator in a if statement was the cause. is it not supported?

Edit
also found out you can't add a mapped list using addAll as it throws this error

type 'MappedListIterable<$Value?, dynamic>' is not a subtype of type 'Iterable<$Value>' of 'iterable'

[Ethan]

Will be fixed in v0.7. In the meantime you can avoid this by not using the word "label" which is a keyword in dart

[Ethan]

Fixed in v0.7.0
