my flutter version:

Flutter 1.17.5 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 8af6b2f038 (13 days ago) • 2020-06-30 12:53:55 -0700
Engine • revision ee76268252
Tools • Dart 2.8.4

the version of floor,floor_generator and build_runner are as below :

environment:
  sdk: ">=2.7.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  cupertino_icons: ^0.1.3
  floor: ^0.13.0

dev_dependencies:
  flutter_test:
    sdk: flutter
  floor_generator: ^0.13.0
  build_runner: ^1.7.3

in the main.dart i build my database using $FloorAppDatabase :

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  var db = await $FloorAppDatabase.databaseBuilder('mydb.db').build();
  runApp(MyApp(db));
}

and in the android folder GeneratedPluginRegistrant.java:

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);
      io.flutter.plugins.flutter_plugin_android_lifecycle.FlutterAndroidLifecyclePlugin.registerWith(shimPluginRegistry.registrarFor("io.flutter.plugins.flutter_plugin_android_lifecycle.FlutterAndroidLifecyclePlugin"));
    flutterEngine.getPlugins().add(new io.flutter.plugins.imagepicker.ImagePickerPlugin());
    flutterEngine.getPlugins().add(new io.flutter.plugins.pathprovider.PathProviderPlugin());
    flutterEngine.getPlugins().add(new io.flutter.plugins.sharedpreferences.SharedPreferencesPlugin());
    flutterEngine.getPlugins().add(new com.tekartik.sqflite.SqflitePlugin());
  }
}

and MainActivity.kt:

import android.os.Bundle
import io.flutter.app.FlutterActivity
import io.flutter.plugins.imagepicker.ImagePickerPlugin


class MainActivity : FlutterActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        ImagePickerPlugin.registerWith(
                registrarFor("io.flutter.plugins.imagepicker.ImagePickerPlugin"))

    }

}

Answer 1

This happen due to the newly added dependencies, where in my case the following command worked. Go to the terminal and then

flutter clean

And re run the project

Answer 2

I finally found my answer. I must add Sqflite plugin in my MainActivity: SqflitePlugin.registerWith(registrarFor("com.tekartik.sqflite.SqflitePlugin"))

my MainActivity changed as below:

import android.os.Bundle
import io.flutter.app.FlutterActivity
import io.flutter.plugins.imagepicker.ImagePickerPlugin
import com.tekartik.sqflite.SqflitePlugin


class MainActivity : FlutterActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        ImagePickerPlugin.registerWith(
                registrarFor("io.flutter.plugins.imagepicker.ImagePickerPlugin"))
        SqflitePlugin.registerWith(registrarFor("com.tekartik.sqflite.SqflitePlugin"))

    }

}
