How to convert int timestamp to DateTime in json_serializable flutter json dart flutter 5,142 Solution 1

To convert an int timestamp to DateTime, you need to pass a static method that returns a DateTime result to the fromJson parameter in the @JsonKey annotation.

This code solves the problem and allows the convertion.

@JsonSerializable(nullable: false) class Person { final String firstName; final String lastName; @JsonKey(fromJson: _fromJson, toJson: _toJson) final DateTime dateOfBirth; Person({this.firstName, this.lastName, this.dateOfBirth}); factory Person.fromJson(Map json) => _$PersonFromJson(json); Map toJson() => _$PersonToJson(this); static DateTime _fromJson(int int) => DateTime.fromMillisecondsSinceEpoch(int); static int _toJson(DateTime time) => time.millisecondsSinceEpoch; }

usage

Person person = Person.fromJson(json.decode('{"firstName":"Ada", "lastName":"Amaka", "dateOfBirth": 1553456553132 }')); Solution 2

I use this:

@JsonSerializable() class Person { @JsonKey(fromJson: dateTimeFromTimestamp) DateTime dateOfBirth; ... } DateTime dateTimeFromTimestamp(Timestamp timestamp) { return timestamp == null ? null : timestamp.toDate(); } Share: 5,142
