E/flutter: [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: DioError [DioErrorType.DEFAULT]: HandshakeException: Handshake error in client (OS Error: CERTIFICATE_VERIFY_FAILED: certificate is not yet valid(handshake.cc:352)) null

[ngu2008]

1、更新pubspec.yaml dio为 dio: ^2.1.0 2、修改DioManager类为

class DioManager { Dio _dio;

DioManager._internal() { _dio = new Dio(); (_dio.httpClientAdapter as DefaultHttpClientAdapter).onHttpClientCreate = (client) { client.badCertificateCallback = (X509Certificate cert, String host, int port) { return true; }; }; }

static DioManager singleton = DioManager._internal();

factory DioManager() => singleton;

get dio { return _dio; } }
