告诉ProGuard忽略flutter_blue（_plus）文件。
1.将proguard-rules.pro文件添加到应用程序文件夹
1.请确保您的应用程序build.gradle中引用了该文件，例如：就像这样

  1. android {
  2.   buildTypes {
  3.     release {
  4.       minifyEnabled true
  5.       shrinkResources true
  6.       proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
  7.     }
  8.   }
  9. }

1.实际告诉ProGuard在pro guard-rules.pro文件中忽略什么。选择您实际使用的库的行。

  1. # for flutter_blue_plus
  2. -keep class com.boskokg.flutter_blue_plus.** { *; }
  4. # for flutter_blue
  5. -keep class com.pauldemarco.flutter_blue.** { *; }
