无法使用 SQLJocky 服务（未定义的类 'SHA1' 和其他错误）

Question

如果我尝试为我的飞镖应用程序提供这些错误：

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

我没有使用 SQLJocky 的任何功能，这些是我的导入：

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';

我的 pubspec.yaml：

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

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

在它看起来像这样之前：

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

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

但由于此错误，我不得不更改它：

因为每个版本的 build_runner 都依赖于加密 >=0.9.2 =0.9.2 =0.6.1 取决于转换 ^2.0.1 和 sqljocky >=0.7.0 取决于加密 ^0.9.0，build_runner >=0.6.1 不兼容 sqljocky >=0.7.0。所以，因为 MyDartPage 既依赖于 sqljocky ^0.14.0 和 build_runner ^0.9.0，版本求解失败。

我的飞镖版本是：

Dart VM 版本：2.0.0-dev.67.0（2018 年 7 月 3 日星期二 18:17:07 +0200） "windows_x64"

如何修复这两个错误？

我使用 SQLJocky5 解决了问题，但在 Dart 2 上我必须通过 PR 来解决这个问题： https://github.com/dart-db/sqljocky5/pull/10
