How to parse json lists in flutter

Question

How can we parse such type of List data in Flutter? I tried different models but failed. Following is the data:

[
    {
        "course":"Computer Architecture Fall 2018 - KHI",
        "pending_assignment":[
            {
                "name":"OOAD Project Fall 2018 Section B & D",
                "dueDate":"Dec 14, 2018 10:00 pm"
            }
        ]
    },
    {
        "course":"Object Oriented Analysis and Design Fall 2018 - KHI",
        "pending_assignment":[
            {
                "name":"OOAD Project Fall 2018 Section B & D",
                "dueDate":"Dec 14, 2018 10:00 pm"
            }
        ]
    }
]

"I tried different models but failed" what have you tried? How did you fail? flutter.io/docs/development/data-and-backend/json — Günter Zöchbauer

I tried the method defined there, but my data is in the form of list if you check it properly, and there is no such definition for that — Hassan Afzal

You need to (de)serialize each entry myList.map((item) => deserializeJson(item)).toList() I made up deserializeJson. Replace it with the code that does the deserialization or parsing. — Günter Zöchbauer

As you can check with this website (https://jsonformatter.org/json-parser), that JSON is not valid and contains errors.

For how to parse JSON in general, you can use the json.decode(jsonString); function from the dart:convert package. For more information on that you can check out this site: https://flutter.io/docs/development/data-and-backend/json
