refresh method
Requests updated information from the Reddit API and updates the current object properties.
Implementation
Future<dynamic> refresh() async {
final response = await reddit.get(infoPath, params: infoParams);
if (response is Map) {
_data = response;
} else if (response is List) {
// TODO(bkonyi): this is for populating a Submission, since requesting
// Submission returns a list of listings, containing a Submission at [0]
// and a listing of Comments at [1]. This probably needs to be changed
// at some point to be a bit more robust, but it works for now.
_data = response[0]['listing'][0].data;
return [this, response[1]['listing']];
} else {
throw DRAWInternalError('Refresh response is of unknown type: '
'${response.runtimeType}.');
}
return this;
}
