Question

我在多个插件中有问题

image_picker：^ 0.6.2 + 3，位置：^ 2.3.5，...

我确实做得很干净，但没有任何改变

Android设备： SM-N900

Android版本： 5.0

MainActivity

import androidx.annotation.NonNull;

import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.GeneratedPluginRegistrant;

public class MainActivity extends FlutterActivity {
  @Override
  public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
    GeneratedPluginRegistrant.registerWith(flutterEngine);
  }
}

GeneratedPluginRegistrant

package io.flutter.plugins;

import androidx.annotation.Keep;
import androidx.annotation.NonNull;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.embedding.engine.plugins.shim.ShimPluginRegistry;

/**
 * Generated file. Do not edit.
 * This file is generated by the Flutter tool based on the
 * plugins that support the Android platform.
 */
@Keep
public final class GeneratedPluginRegistrant {
  public static void registerWith(@NonNull FlutterEngine flutterEngine) {
    ShimPluginRegistry shimPluginRegistry = new ShimPluginRegistry(flutterEngine);
    flutterEngine.getPlugins().add(new io.flutter.plugins.deviceinfo.DeviceInfoPlugin());
      io.flutter.plugins.imagepicker.ImagePickerPlugin.registerWith(shimPluginRegistry.registrarFor("io.flutter.plugins.imagepicker.ImagePickerPlugin"));
      com.lyokone.location.LocationPlugin.registerWith(shimPluginRegistry.registrarFor("com.lyokone.location.LocationPlugin"));
    flutterEngine.getPlugins().add(new io.flutter.plugins.pathprovider.PathProviderPlugin());
      flutter.plugins.screen.screen.ScreenPlugin.registerWith(shimPluginRegistry.registrarFor("flutter.plugins.screen.screen.ScreenPlugin"));
    flutterEngine.getPlugins().add(new io.flutter.plugins.sharedpreferences.SharedPreferencesPlugin());
      com.tekartik.sqflite.SqflitePlugin.registerWith(shimPluginRegistry.registrarFor("com.tekartik.sqflite.SqflitePlugin"));
      altercode.xyz.uniqueidentifier.UniqueIdentifierPlugin.registerWith(shimPluginRegistry.registrarFor("altercode.xyz.uniqueidentifier.UniqueIdentifierPlugin"));
    flutterEngine.getPlugins().add(new io.flutter.plugins.urllauncher.UrlLauncherPlugin());
  }
}

我的例外之一是：

还有我的代码：

var _locationService = new Location();

bool serviceStatus = await _locationService.serviceEnabled();
