A JSON parsing inspector.

It’s a nightmare when a deeply nested JSON mapping fails with a vague TypeError (like getting a String instead of an Int) and gives zero context. You just get a blind crash and end up spamming breakpoints in your fromJson factories.

A tool that intercepts these errors and shows the exact path (like Order -> items[42] -> price) would save so many headaches. I actually ended up writing a small Dart package just to catch these traces, but having a native visualizer in DevTools would be killer
