You can use a .sql file that contains your DB script.

First,add the script file to assets.

Then, import the following packages:

import 'package:path/path.dart';

import 'package:sqflite/sqflite.dart';

import 'package:flutter/services.dart' show rootBundle;

finally, use the following code

void _createDb() async 
{
      final database = openDatabase( join( await getDatabasesPath(), 'mydb.db'),
      onCreate: (db, version) async  
      {
          // call database script that is saved in a file in assets
          String script =  await rootBundle.loadString("assets\\db\\script.sql");
          List scripts = script.split(";");
          scripts.forEach((v) 
          {
              if(v.isNotEmpty ) 
              {
                   print(v.trim());
                   db.execute(v.trim());
              }
          });
       },
       version: 1,
       );
}
