Basic Rules of Sqlite, you need to remember

1. sqflite is works on Top of SQLite Database
2. so , when ever flutter plugin creates the database ,it was availible for native code (verify folder structure)
3. You can OpenDatabase by giving Database Path to SQLiteDatabase on Native Android or IOS
4. finally you can Read table data by query()

    private fun accessDB(){

    try {
        GlobalScope.launch {

            var db:SQLiteDatabase = SQLiteDatabase.openDatabase(getDatabasePath("epistle.db").absolutePath,null,SQLiteDatabase.OPEN_READWRITE);

            Log.d(MainActivity::class.java.name , "Database Path "+db.path.toString())
            Log.d("" , "Database version "+db.version.toString())

            var cursor = db.query("userInfo",null,null,null,null,null,null)

            cursor?.let {
                while (cursor.moveToNext()){

                    var columnNames =cursor.columnNames

                    columnNames.forEach {
                        Log.d(
                                MainActivity::class.java.name,
                                "$it "+cursor.getString(cursor.getColumnIndex(it))
                        )
                    }

                }
            }

        }

    }catch (e:Exception){
        e.printStackTrace();
    }
}
