renderTip function

String renderTip(DRObject message, { required NameOf nameOf, String? self, DRLocale locale = zhCN, })

群提示的文字（《消息/3.接口设计》第 12.3 节的各种 kind）。self 为本人时显示“你”。

Implementation

String renderTip(DRObject message, {required NameOf nameOf, String? self, DRLocale locale = zhCN}) {
  final l = locale;
  final b = _body(message);
  String name(String u) => self != null && u == self ? l.you : nameOf(u);
  final operator = b['operator'] is String ? name(b['operator']! as String) : '';
  String fill(String key, Map<String, String> values) => formatTemplate(_t(l.tip, key), values);
  final hasOperator = b['operator'] is String && (b['operator']! as String).isNotEmpty;
  switch (b['kind']) {
    case 'group_created':
      return fill('group_created', {'operator': operator});
    case 'members_joined':
      final members = _names(b['members'], b['joined_count'], name, l);
      if (!hasOperator) return fill('members_joined', {'members': members});
      if (b['joined_via'] == 'link') return fill('members_joined_link', {'members': members, 'operator': operator});

    case 'group_renamed':

    case 'group_status_changed':
      return _t(l.tip, b['status'] == 'disabled' ? 'group_disabled' : 'group_enabled');
