[Mobile] How can I add new message on last by manually

[ghost]

Dear Developers,

Thank you very much for your support and I am sorry I don't know how to add a new message at end of the data with attributes manually.

Could you please kindly tell me, how can I add a new message by inserting it at end of the document with the attribute manually?

Thank you very much

delta.insert('a new message', {'bold': true});

Thank you very much @MagTuxGit .
But when I use quillController.document.toDelta().insert('(edited)', {'color' : '#888888'});, it doesn't add that message.
Could you please kindly help me 🙏
Thank you very much

I would like to show (edited) at end of message.

When I use the following code, it can show (edited) at end of message but last message ending with header 1, "(edited)" is also showing header attribute

      quillController!.document.insert(quillController!.document.length - 1,
          ' ${AppLocalizations.of(context)!.message_edited}');
      quillController!.document.format(quillController!.document.length - (edited.length),
          edited.length, ColorAttribute('#888888'));
      quillController!.document.format(
          quillController!.document.length - (edited.length), edited.length, SmallAttribute());

before adding "(edited)", log output:

[{"insert":"Test","attributes":{"background":"#004d40"}},{"insert":" "},{"insert":"22","attributes":{"code":true}},{"insert":"\n","attributes":{"header":1}}]

After adding "(edited)", log output

[{"insert":"Test","attributes":{"background":"#004d40"}},{"in
sert":" "},{"insert":"22 ","attributes":{"code":true}},{"insert":"(edited)","attributes":{"code":true,"color":"#888888","small":true}},{"insert":"\n","attributes":{"header":1}}]

Actually I don't understand what the result are you expecting. It would be better to specify what do you want to get.

I believe there is another more correct way to resolve your issue, but I'll try to answer your question:

    bool isSecondUtf16Surrogate(int value) {
      return value & 0xFC00 == 0xDC00;
    }
    int charLength = 1;
    if (isSecondUtf16Surrogate(stringValue.codeUnitAt(cursorPosition-1))) {
      charLength = 2;
    }

I didn't check this code so it may not work for you.

Thank you very much @MagTuxGit

I think it is better to support the delete function in the library. If I would like to delete the previous char from the current cursor position, just call library.delete method and it will delete manually.

[MagTuxGit]

I don't understand what are you trying to achieve. Why do you want to delete manually?

[ghost]

Yes @MagTuxGit, I would like to do backspace remove character manually, because I using with emoji picker, in emojji picker when backspace, I would like to delete character from current focused cursor position at quill editor.

Thank you very much @MagTuxGit

bool isSecondUtf16Surrogate(int value) {
     return value & 0xFC00 == 0xDC00;
   }
   int charLength = 1;
   if (isSecondUtf16Surrogate(stringValue.codeUnitAt(cursorPosition-1))) {
     charLength = 2;
   }

This is code is working well.

Thank you very much for many supporting to me 🙏
