Steps to Reproduce

Sorry for my bad English, hope you understand.
When I intentionally parse the json by entering the wrong key, the catch block is not triggered.
Wrong key: title1
Right key: title

Future<void> _testing() async {
  final dio = Dio();
  try {
    final response = await dio.get('https://api.sampleapis.com/coffee/hot');
   // ISSUE: "title1" is wrong key. Right key is "title".
    final listBody = (response.data as List).map((e) => e['title1'] as String).toList(); 
    for(var i in listBody){
      log(i, name: 'Try');
    }
  } on Exception catch (e) {
    log(e.toString(), name: 'Catch');
  }
}

JSON:

[
    {
        "title": "Black Coffee",
        "description": "Svart kaffe är så enkelt som det kan bli med malda kaffebönor dränkta i hett vatten, serverat varmt. Och om du vill låta fancy kan du kalla svart kaffe med sitt rätta namn: café noir.",
        "ingredients": [
            "Coffee"
        ],
        "image": "https://images.unsplash.com/photo-1494314671902-399b18174975?auto=format&fit=crop&q=80&w=1887&ixlib=rb-4.0.3&ixid=M3wxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8fA%3D%3D",
        "id": 1
    },
]

Expected Result

catch block triggered when parsing json to an object fails.

Actual Result

It throws TypeError, which is not a subtype of Exception that you're catching.

What is the best practice in this case?

@AlexV525 What is the best practice in this case?

In this case, it should catch anything.
