Не работает с SQLJocky (неопределенный класс SHA1 и другие ошибки)

если я попытаюсь обслужить свое приложение для дротиков, я получу следующую ошибку:

    Please fix all errors before compiling (warnings are okay). }

Я не использую никаких функций SQLJocky, это мой импорт:

import 'dart:async';
import 'dart:convert';

import 'package:angular/angular.dart';
import 'package:angular_components/angular_components.dart';
import 'package:sqljocky/sqljocky.dart';
import 'package:sqljocky/utils.dart';
import 'package:options_file/options_file.dart';

Мой pubspec.yaml:

name: MyDartPage
description: A web app that uses AngularDart Components
# version: 1.0.0
# homepage: https://www.example.com
# author: Mattia <[email protected]>

environment:
  sdk: '>=2.0.0-dev.66.0 <2.0.0'

dependencies:
  angular: any
  angular_components: any
  sqljocky: any


dev_dependencies:
  angular_test: any
  build_runner: any
  build_test: any
  build_web_compilers: any
  test: any

раньше это выглядело так:

name: MyDartPage
description: A web app that uses AngularDart Components
# version: 1.0.0
# homepage: https://www.example.com
# author: Mattia <[email protected]>

environment:
  sdk: '>=2.0.0-dev.66.0 <2.0.0'

dependencies:
  angular: ^5.0.0-beta
  angular_components: ^0.9.0-beta
  sqljocky: ^0.14.0

dev_dependencies:
  angular_test: ^2.0.0-beta
  build_runner: ^0.9.0
  build_test: ^0.10.2
  build_web_compilers: ^0.4.0
  test: ^1.0.0

но мне пришлось изменить его из-за этих ошибок:

Поскольку каждая версия build_runner зависит от crypto> = 0.9.2 ‹3.0.0, а crypto> = 0.9.2‹ 2.0.1 зависит от convert ^ 1.0.0, каждая версия build_runner требует convert ^ 1.0.0 или crypto ^ 2.0 .1. И поскольку build_runner> = 0.6.1 зависит от convert ^ 2.0.1, а sqljocky> = 0.7.0 зависит от crypto ^ 0.9.0, build_runner> = 0.6.1 несовместим с sqljocky> = 0.7.0. Итак, поскольку MyDartPage зависит как от sqljocky ^ 0.14.0, так и от build_runner ^ 0.9.0, определение версии не удалось.

Моя версия дротика:

Версия виртуальной машины Dart: 2.0.0-dev.67.0 (Вт 3 июля 18:17:07 2018 +0200) на "windows_x64"

Как исправить обе ошибки?
