This might be more of a Dart question than Flutter, but it originates from a requirement I have in a Flutter project.

I am to receive a definition of a field in a form, and in Flutter, I am to display a dynamic widget that is created according to the field definition.

Say for example I receive a json file describing a DateTime field, and it describes this field specifically to show only the date.

I believe the solution should be a generated file, that holds a map between a field definition and an instance of widget, like so:

{
    "DateTimeDateOnly": "MyWidget(prop1: hardcoded value, prop2: dataObject.fieldValue)"
}

I was wondering:

1. Is this possible?
2. How can I create the widget dynamically, in a way that for every field I’ll need to display in the same manner, I’ll get the same widget?
3. Once the definition itself is updated(I get a new json), how do I update the mapping from the field definition to its widget representation?
