updateRecentEmoji method

void updateRecentEmoji(List<RecentEmoji> recentEmoji, { bool refresh = false, })

Update recentEmoji list from outside using EmojiPickerUtils

Implementation

void updateRecentEmoji(
  List<RecentEmoji> recentEmoji, {
  bool refresh = false,
}) {
  _recentEmoji = recentEmoji;
  // Only mutate the displayed category data when we actually intend to
  // refresh the UI. `_categoryEmoji` is shared by reference with `_state`,
  // so mutating it here without a `setState()` would still surface the new
  // recent list on the next unrelated rebuild triggered by a parent widget
  // (e.g. the RECENT tab re-ordering under the user). The persisted store is
  // already updated by the caller, so the change is not lost - it simply
  // becomes visible on the next explicit refresh instead of leaking early.
  if (!refresh) {
    return;
  }
  final recentTabIndex = _categoryEmoji.indexWhere(
    (element) => element.category == Category.RECENT,
  );
  if (recentTabIndex != -1) {
    _categoryEmoji[recentTabIndex] = _categoryEmoji[recentTabIndex].copyWith(
      emoji: _recentEmoji.map((e) => e.emoji).toList(),
    );
    if (mounted) {
      setState(() {});
    }
  }
