[Other]: <Replace AAR in flutter project, send text message ok, send picture get panic> #1018
Description
What would you like to share?
I have changed some code in the repo, then I build aar to flutter project. I use the flutter sdk in locally. However, after I rebuild the flutter project, When I send Text message, it is ok, when it to picture, voices, I found a panic in my log.
And I try to find out why it happens,
func (c *Conversation) SendMessage(ctx context.Context, s *sdk_struct.MsgStruct, recvID, groupID string, p *sdkws.OfflinePushInfo, isOnlineOnly bool) (*sdk_struct.MsgStruct, error) {
filepathExt := func(name ...string) string {
for _, path := range name {
fmt.Println("filepathExt", path)
if ext := filepath.Ext(path); ext != "" {
fmt.Println("filepathExt ext", ext)
return ext
}
}
fmt.Println("filepathExt ext empty")
return ""
}
options := make(map[string]bool, 2)
lc, err := c.checkID(ctx, s, recvID, groupID, options)
if err != nil {
return nil, err
}
callback, _ := ctx.Value("callback").(open_im_sdk_callback.SendMsgCallBack)
log.ZDebug(ctx, "before insert message is", "message", *s)
if !isOnlineOnly {
oldMessage, err := c.db.GetMessage(ctx, lc.ConversationID, s.ClientMsgID)

return nil, err
}
err = c.db.InsertSendingMessage(ctx, &model_struct.LocalSendingMessages{

...Then I test in project sdk-core, it is ok. But in flutter, I have logs below

Then I have no idea about why this will panic,
