New in v1.9.0

Message Status Enhancements

All bubble widgets now accept timestamp, isEdited, isForwarded, and messageId parameters.

BubbleNormal(
  text: 'This message was edited',
  isSender: true,
  color: Color(0xFFE8E8EE),
  tail: true,
  seen: true,
  timestamp: '12:34 PM',
  isEdited: true,
),

BubbleNormal(
  text: 'Forwarded from another chat',
  isSender: false,
  color: Color(0xFF1B97F3),
  tail: true,
  textStyle: TextStyle(color: Colors.white, fontSize: 16),
  isForwarded: true,
  timestamp: '12:35 PM',
),

Swipe Actions

Wrap any bubble with SwipeableBubble to add swipe-to-reply and swipe-to-delete gestures.

SwipeableBubble(
  onSwipeRight: () => print('Reply triggered'),
  onSwipeLeft: () => print('Delete triggered'),
  swipeThreshold: 64.0,
  enableHaptics: true,
  child: BubbleNormal(
    text: 'Swipe me!',
    isSender: false,
    color: Color(0xFF1B97F3),
    tail: true,
    textStyle: TextStyle(color: Colors.white, fontSize: 16),
  ),
),

Parameter	Type	Default	Description
child	Widget	required	The bubble to wrap
onSwipeRight	VoidCallback?	null	Called on swipe-right (reply)
onSwipeLeft	VoidCallback?	null	Called on swipe-left (delete)
swipeThreshold	double	64.0	Drag distance to trigger
enableHaptics	bool	true	Haptic feedback on threshold
rightActionColor	Color	Colors.blue	Background for right swipe
leftActionColor	Color	Colors.red	Background for left swipe
rightActionIcon	Icon	Icons.reply	Icon for right swipe
leftActionIcon	Icon	Icons.delete	Icon for left swipe

Message Groups / Clustering

Use BubbleGroupBuilder to automatically group consecutive messages from the same sender. Only the last message in each group shows a tail.

final messages = ['Hello!', 'How are you?', 'Good, thanks!'];
final senders  = ['alice', 'alice', 'bob'];

BubbleGroupBuilder(
  itemCount: messages.length,
  senderIdOf: (i) => senders[i],
  itemBuilder: (context, i, info) => BubbleNormal(
    text: messages[i],
    isSender: senders[i] == 'bob',
    tail: info.showTail,
    color: senders[i] == 'bob'
        ? const Color(0xFFE8E8EE)
        : const Color(0xFF1B97F3),
  ),
)

For advanced control, use MessageGroupHelper.compute() directly to get GroupInfo for each message:

final List<GroupInfo> groups = MessageGroupHelper.compute(
  senderIds: senders,
  timestamps: timestamps,  // optional
  threshold: const Duration(minutes: 2),
);

// groups[i].showTail  — whether to show the tail
// groups[i].showAvatar — whether to show the avatar
// groups[i].isGroupStart — first message in group (add extra top spacing)

Voice Message Waveform

BubbleNormalAudio now supports waveform visualization and playback speed control.

BubbleNormalAudio(
  color: Color(0xFFE8E8EE),
  duration: duration.inSeconds.toDouble(),
  position: position.inSeconds.toDouble(),
  isPlaying: isPlaying,
  isLoading: isLoading,
  isPause: isPause,
  onSeekChanged: _changeSeek,
  onPlayPauseButtonClick: _playAudio,
  sent: true,
  // Waveform visualization
  waveformData: [0.2, 0.8, 0.5, 0.9, 0.4, 0.7, 0.6, 0.3, 0.8, 0.5],
  waveformActiveColor: Color(0xFF1B97F3),
  waveformInactiveColor: Colors.grey,
  // Playback speed
  showPlaybackSpeed: true,
  playbackSpeed: _playbackSpeed,
  onPlaybackSpeedChanged: (speed) => setState(() => _playbackSpeed = speed),
),

waveformData is a List<double> of normalized bar heights (0.0–1.0). Tapping or dragging on the waveform seeks to that position. The speed button cycles 1x → 1.5x → 2x → 1x.
