Flutter app error - type 'Timestamp' is not a subtype of type 'DateTime'

Question

I\'m fetching data cloud firestore & trying to show in my app by using the following piece of code.

new Text(timeago.format(document.data[\'tripDoc\'][\'         


        

Answer 1

add toDate() method .It will work

DateTime dateTime = documents[i].data["duedate"].toDate();

Answer 2

Firestore is returning a Timestamp object, which consists of seconds and nanoseconds. Oddly, on iOS you can indeed just use a .toDate() and it works. But that breaks on Android as toDate() is not a method. So you can do a platform check if you want, but the universal solution is to use Firestore's Timestamp:

import 'package:cloud_firestore/cloud_firestore.dart';

DateTime _convertStamp(Timestamp _stamp) {

  if (_stamp != null) {

    return Timestamp(_stamp.seconds, _stamp.nanoseconds).toDate();

    /*
    if (Platform.isIOS) {
      return _stamp.toDate();
    } else {
      return Timestamp(_stamp.seconds, _stamp.nanoseconds).toDate();
    }
    */

  } else {
    return null;
  }
}

and then pass your model to it:

  SomeModel.fromJson(Map<String, dynamic> parsedJson) {
    updatedAt = _convertStamp(parsedJson['updatedAt']);
  }
