this is Laravel's default error response:
{
"message": "The given data was invalid.",
"errors": {
"phone": [
"validation.exists"
]
}
}
and the values of "errors" are different in each error and request. how can I get "validation.exists" message?
import 'dart:convert';
String networkError(String errorValue) {
String value = "";
if (jsonDecode(errorValue)['errors'] != null) {
Map<String, dynamic> errors = jsonDecode(errorValue)['errors'];
final error = errors.values.first;
if (!(error is String) && error.length > 0) {
value = error[0];
} else {
value = error;
}
} else if (jsonDecode(errorValue)["message"] != null) {
value = jsonDecode(errorValue)["message"];
} else {
value = jsonDecode(errorValue)["error"];
}
return value;
}
usage
Future<String> fetch() async {
var url = Uri.parse('https://example.com/whatsit/create');
var response =
await http.post(url, body: {'name': 'doodle', 'color': 'blue'});
print('Response status: ${response.statusCode}');
print('Response body: ${response.body}');
if (response.statusCode == 200) {
return "Success YES";
} else {
//!HERE ON ERROR
return networkError(response.body.toString());
}
}
