    • @dbestech
      @dbestech  2 года назад +1

      You are welcome. When you decode json from it returns list. List includes map inside. But anyway, you can access that list by index. for example list[i]["propertyname"], like this. Yes we will make e-commerce app.

    To play video as index

    • @dbestech
      @dbestech  Год назад

      To play video using index, you don't need to access the file system. You need to keep the track of your video using a list. But lot depends on your actual code.

    We can access only through map or can you access the value like user.name?

    • @dbestech
      @dbestech  2 года назад +1

      I think you need to use like this obj.forEach((key, value){print(value);});
