flutter - 无法启动服务 rekab.app.background_locator.IsolateHolderService

Question

当用户通过单击按钮激活跟踪时，我使用 background_locator 来跟踪 geo_location。然后将该位置发布到 API，该 API 将其记录在数据库中。

该功能在调试模式下工作，但在发布模式下崩溃并出现以下异常：

我通过将这些规则添加到android/app/proguard-rules.pro

# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature

# Gson specific classes
-keep class sun.misc.Unsafe { *; }
#-keep class com.google.gson.stream.** { *; }

# Application classes that will be serialized/deserialized over Gson
-keep class com.google.gson.examples.android.model.** { *; }
