我正在尝试在我的 pubspec.yaml 文件中添加 flutter blue，但版本解析失败

Question

我正在尝试在我的 pubspec.yaml 文件中添加 flutter blue，但是版本解析失败但它似乎不支持在同一个 pubspec.yaml 文件中存在 flutter reactive ble。

以下是我的pubspec.yaml文件：

environment:
  sdk: ">=2.2.2 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  image_picker:
  http: ^0.12.0+4
  flutter_bloc: ^4.0.0
  equatable: ^1.0.0
  shared_preferences: ^0.5.7
  fluttertoast: ^8.0.8
  flutter_spinkit: "^4.1.2"
  intl: ^0.16.1
  auto_orientation: 2.1.0
  exif: ^1.0.2
  image: ^2.1.4
  flutter_exif_rotation: 0.3.0
  animated_floatactionbuttons: ^0.1.0
  ffi: ^1.0.0
  provider: ^4.0.5
  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

  get: ^4.6.1
  flutter_reactive_ble: ^3.1.1+1
  js: ^0.6.3
  flutter_launcher_icons: ^0.8.1


dev_dependencies:
  flutter_test:
    sdk: flutter

在终端，当我运行，

flutter pub add flutter_blue

我收到以下错误：

Because flutter_blue <0.4.0 requires SDK version >=1.8.0 <2.0.0 and flutter_blue >=0.4.0 <0
.4.2 depends on protobuf ^0.9.1, flutter_blue <0.4.2 requires protobuf ^0.9.1.
And because flutter_blue >=0.4.2 <0.6.0 depends on protobuf ^0.10.5, flutter_blue <0.6.0 re
quires protobuf ^0.9.1 or ^0.10.5.
And because flutter_blue >=0.6.0 <0.6.1 depends on protobuf ^0.13.12 and flutter_blue >=0.6
.1 <0.6.3+1 depends on protobuf ^0.14.1, flutter_blue <0.6.3+1 requires protobuf ^0.9.1 or
^0.10.5 or ^0.13.12 or ^0.14.1.
And because flutter_blue >=0.6.3+1 <0.7.2 depends on protobuf ^1.0.0 and flutter_blue ^0.7.
2 depends on protobuf ^1.0.1, flutter_blue <0.8.0 requires protobuf ^0.9.1 or ^0.10.5 or ^0
.13.12 or ^0.14.1 or >=1.0.0 <2.0.0.
And because flutter_reactive_ble ^3.0.0 depends on protobuf ^2.0.0 and flutter_blue >=0.8.0
 depends on convert ^3.0.0, if flutter_reactive_ble ^3.0.0 and flutter_blue any then conver
t ^3.0.0.
And because attendanceapp depends on exif ^1.0.2 which depends on convert ^2.0.0, flutter_r
eactive_ble ^3.0.0 is incompatible with flutter_blue.
So, because attendanceapp depends on both flutter_reactive_ble ^3.1.1+1 and flutter_blue an
y, version solving failed.
pub finished with exit code 65

现在，如果更改为 A SDK 版本，如前所述，我会收到很多其他错误。除 flutter blue 外，所有依赖都匹配此项目。

该项目在不添加 flutter blue 的情况下完全可以正常工作。

如果我升级包，我仍然无法将 flutter blue 与我正在使用的其他依赖项相匹配。

摸不着头脑，不知道应该用哪个flutter blue版本。

请有人帮助我。

我将 flutter_blue 设置为 0.7.0，将 flutter_reactive_ble 设置为 2.7.3。我不确定这么旧的版本是否包含您需要的所有功能。但是 pug get 显示这组版本没有错误
