To obtain the total number of records in a table using Flutter SQFLite, you can use the rawQuery method to execute an SQL query that selects and counts all the records in the table.

Here's an example code snippet that demonstrates how to do this for a table called my_table:

import 'package:sqflite/sqflite.dart';

Future<int> getTotalRecordsCount() async {
  Database db = await openDatabase('my_database.db');
  int count = Sqflite.firstIntValue(await db.rawQuery('SELECT COUNT(*) FROM my_table'));
  return count;
}

In this code, we first open the database using the openDatabase method. Then, we execute an SQL query using the rawQuery method, which selects and counts all the records in the my_table table. Finally, we return the count as an int value.

Note that the firstIntValue method is used to extract the count from the query result. This method returns the first value from the first row of the result set as an int value. In this case, the value is the count of all the records in the table.
