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

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']['docCreatedOn'])),

I'm using ```timeago``` dart package to format that. But, after making updating to latest cloud firestore plugin I'm getting this error -

Another exception was thrown: type 'Timestamp' is not a subtype of type 'DateTime'

Can't able to understand how to parse this 'TimeStamp' object to 'DateTime'. Because ```timeago``` plugin need data in DateTime object format.

DateTime.fromMillisecondsSinceEpoch(timeStamp);
DateTime.fromMicrosecondsSinceEpoch(timeStamp);

var date = DateTime.fromMillisecondsSinceEpoch(timestamp)

```.toDate()``` worked for me. Now the modified code is -

new Text(timeago.format(document.data['tripDoc']['docCreatedOn'].toDate()))

Hope, it'll help someone.

I think this is more reliable

DateTime updateDateTime = DateTime.fromMillisecondsSinceEpoch(
map['updatedatetime'].millisecondsSinceEpoch);

For some funny reason, I can't use toDate() on Android. Have to use it for iOS. So I'm forced to use a platform check like this:

Theme.of(context).platform == TargetPlatform.iOS
? DateFormat('dd MMM kk:mm').format(document['timestamp'].toDate())
: DateFormat('dd MMM kk:mm').format(document['timestamp'])

You can try this..

timeago.format(DateTime.tryParse(timestamp))
like in yours it will be

timeago.format(DateTime.tryParse(document.data['tripDoc']['docCreatedOn']))

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']);
}

Ios and Android will not receive same type. Ios receive the timestamps as TimeStamp and Android receive it as DateTime already. So for fixing this issue I just created this little function. This will return a DateTime and let use format it etc.

import 'dart:io';

import 'package:cloud_firestore/cloud_firestore.dart';

DateTime parseTime(dynamic date) {
return Platform.isIOS ? (date as Timestamp).toDate() : (date as DateTime);
}

add toDate() method .It will work



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