详情请参考Flutter高仿微信-第44篇-群聊，这里只是群聊的语音实现代码。

实现代码：

//我的语音
Widget meVoiceWidget(){return InkWell(onTap: () {widget.clickVoiceCallback(true);setState(() {widget.chatBean.isPlayVoice = true;});//点击语音AudioPlayer.getInstance().playLocal(widget.chatBean.voiceLocal??"", callback: (data){//录音回调setState(() {widget.chatBean.isPlayVoice = false;});});},child : Container(width: 120,height: 40,padding: EdgeInsets.symmetric(vertical: 4.0, horizontal: 2.0),decoration: BoxDecoration(borderRadius: BorderRadius.all(Radius.circular(1.0),),color: Color(0xFF9EEA6A),),child: Row(crossAxisAlignment: CrossAxisAlignment.center,mainAxisAlignment: MainAxisAlignment.center,children: [Text("${widget.chatBean.second}''"),SizedBox(width: 4,),widget.chatBean.isPlayVoice?Image.asset("assets/chat/wn_chat_me_animator.gif", height: 24,):Image.asset("assets/chat/wn_chat_me_volume_3.png", height: 24,),],),));
}

//朋友的语音
Widget toVoiceWidget(){return InkWell(onTap: () {setState(() {widget.chatBean.isPlayVoice = true;});LogUtils.d("点击语音");AudioPlayer.getInstance().playLocal(widget.chatBean.voiceLocal??"", callback: (data){LogUtils.d("录音回调：${data}");setState(() {widget.chatBean.isPlayVoice = false;});});},child : Container(width: 120,height: 40,padding: EdgeInsets.symmetric(vertical: 4.0, horizontal: 2.0),decoration: BoxDecoration(borderRadius: BorderRadius.all(Radius.circular(5.0),),color: Color(0xFFEDEDED)),child: Row(crossAxisAlignment: CrossAxisAlignment.center,mainAxisAlignment: MainAxisAlignment.center,children: [widget.chatBean.isPlayVoice?Image.asset("assets/chat/wn_chat_other_animator.gif", height: 34,):Image.asset("assets/chat/wn_chat_other_volume_3.png",  height: 34,),SizedBox(width: 4,),Text("${widget.chatBean.second}''"),],),));
}

//刷新多媒体(图片、语音、小视频) (先刷新本地，然后小视频压缩完成再慢慢发送)
void _refreshMedia(int type, String mediaURL, String thumbnailFileName, {int mediaSecond=0, String messageId = "" }) async {bool isNetwork = await CommonNetwork.isNetwork();if(!isNetwork) {CommonUtils.showNetworkError(context);return;}String addTime = WnDateUtils.getCurrentTime();//先刷新本地聊天//ChatBean chatBean = ChatBean(fromAccount: widget.account, toAccount: widget.toGroupId,addTime:addTime,messageId: messageId,isRead: 1);GroupChatBean groupChatBean = GroupChatBean(account: widget.account, groupId: widget.toGroupId, addTime: addTime, messageId: messageId);LogUtils.d("群聊刷新：${type}");groupChatBean.contentType = type;groupChatBean.localMediaUrl = mediaURL;groupChatBean.content = thumbnailFileName;groupChatBean.second = mediaSecond;if(type == CommonUtils.CHAT_CONTENT_TYPE_VOICE){//状态变更，向聊天记录中插入新记录setState(() {items.add(groupChatBean);});await GroupChatRepository.getInstance().insertGroupChat(groupChatBean);} jumpToBottom(100);
}

//发送多媒体(图片、语音、小视频)
void _sendMedia(int type, String mediaURL, {int mediaSecond = 0, String messageId = ""}) async {bool isNetwork = await CommonNetwork.isNetwork();if(!isNetwork) {return;}//上传文件GroupChatBean? serverChatBean;String message = "";String addTime = WnDateUtils.getCurrentTime();ChatSendBean chatSendBean = ChatSendBean();chatSendBean.fromAccount = SpUtils.getAccount();chatSendBean.contentType = type;chatSendBean.messageId = messageId;chatSendBean.addTime = addTime;if(type == CommonUtils.CHAT_CONTENT_TYPE_VOICE){//语音serverChatBean = await UploadUtils.getInstance().uploadGroupChatVoice(widget.account, widget.toGroupId, mediaURL, messageId, addTime, mediaSecond);chatSendBean.second = mediaSecond;}chatSendBean.content = serverChatBean?.serverMediaUrl??"";GroupChatRepository.getInstance().updateGroupChatByMessageId(serverChatBean?.messageId??"", serverChatBean?.serverMediaUrl??"");message = jsonEncode(chatSendBean);_sendMessage(message);
