fix: Error on empty action json

[divyanshub024]

Description

Getting error type '_Map<dynamic, dynamic>' is not a subtype of type 'Map<String, dynamic>?' in type cast<…> when passed an empty action json.

{
              "type": "textButton",
              "onPressed": {},
              "child": {
                "type": "text",
                "data": "Forgot password?",
                "style": {
                  "fontSize": 15,
                  "fontWeight": "w500",
                  "color": "#4745B4"
                }
              }
            }

Expected Behavior

{} Empty JSON should act like a null action on call.
Add any other context about the problem here.

Bro, are you making changes to the code? I tried running it based on the example code, but there are a lot of files that it says it can't find.I'm currently using version 0.10.0

It seems like some files haven't been properly adapted or configured. Or is there any version that's stable and usable? I just want to have a try.

Hey @Kimhooo,

This issue seems unrelated to the current thread. Could you please open a new issue for it?

Also, I tested v0.10, and it runs fine on my machine. In the new issue, could you share the output of flutter doctor, the Stac code, the JSON you’re passing, and the full error log you’re encountering? That would help in diagnosing the issue more effectively.

Thanks!
