If you have a list of objects you want to insert, you can do it like this (it's not a very clean code, but it works):

  insertClients(List clients) async {
    final db = await database;
    var buffer = new StringBuffer();
    clients.forEach((c) {
      if (buffer.isNotEmpty) {
        buffer.write(",\n");
      }
      buffer.write("('");
      buffer.write(c.firstName);
      buffer.write("', '");
      buffer.write(c.lastName);
      buffer.write("', '");
      buffer.write(c.address);
      buffer.write("')");
    });
    var raw =
        await db.rawInsert("INSERT Into Clients (firstName,lastName,address)"
            " VALUES ${buffer.toString()}");
    return raw;
  }

I'm using this statement from SQLite:

INSERT INTO 'tablename' ('column1', 'column2') VALUES
                ('data1', 'data2'),
                ('data1', 'data2'),
                ('data1', 'data2');
