We use the module "Users" as example

• create a metadata description: lib/meta/users_meta.dart

import 'module_meta_data.dart';

class UserMeta extends ModuleMetaData  {
  static UserMeta instance = UserMeta.internal();
  UserMeta.internal() : super('Users',
    [
      PropertyMetaData('id', DataType.reference, ':primary:', 'combo'),
      PropertyMetaData('name', DataType.string, ':notnull:', '', size: 64),
      PropertyMetaData('displayName', DataType.string, ':unique:notnull:', '', size: 32),
      PropertyMetaData('email', DataType.string, ':unique:notnull:', '', size: 255),
      PropertyMetaData('role', DataType.reference, ':notnull:', ''),
      PropertyMetaData('created', DataType.datetime, '', ''),
      PropertyMetaData('createdBy', DataType.string, '', '', size: 32),
      PropertyMetaData('changed', DataType.datetime, '', ''),
      PropertyMetaData('changedBy', DataType.string, '', '', size: 32),
    ],
    tableName: 'loginusers',
  );
  factory UserMeta(){
    return instance;
  }
}
