onError method
The callback will be executed on error.
If you want to continue the error , call handler.next
.
If you want to complete the response with some custom data directly,
you can resolve a Response
object with handler.resolve
and other
error interceptor(s) will be skipped.
If you want to complete the response with an error message directly,
you can reject a DioError
object with handler.reject
, and other
error interceptor(s) will be skipped.
Implementation
@override
void onError(DioError err, ErrorInterceptorHandler handler) {
super.onError(err, handler);
try {
_talker.handle(
err,
null,
'''URL: ${err.requestOptions.uri}
METHOD: ${err.requestOptions.method}
${err.response?.statusCode != null ? 'STATUS-CODE: ${err.response?.statusCode}' : ''}''',
);
} catch (_) {
//pass
}
}
