    if (maps.length > 0) {
      for (int i = 0; i < maps.length; i++) {
        employees.add(Employee.fromMap(maps[i]));

This is because the Employee.fromMap expecting Map<String, dynamic> Change your function as follows.

   Future<List<Employee>> getEmployee() async {
        var dbClient = await db;
        List<Map> maps = await dbClient!.query('employee', columns: ['id', 'name','phone']);
        List<Employee> employees = [];
        if (maps.length > 0) {
          for (int i = 0; i < maps.length; i++) {
            employees.add(Employee.fromMap(Map<String, dynamic>.from(maps[i])));
          }
        }
        return employees;
      }
