I'm having problem with coding UI formatting of message box with flutter

Question

Look as you can see here the message box at the bottom should crop to the content but it doesn't as the word doesn't fit so just goes to next line but message box doesn't update.

heres my current code the max width is 0.7 but yeah it should be able to have a lower limit like 0.5 right.

return Padding(
  padding: EdgeInsets.only(
    top: sameUserAsNext ? 4.0 : 10.0,
    bottom: 4.0,
    left: 10.0,
    right: 10.0,
  ),
  child: Align(
    alignment: isCurrentUser ? Alignment.centerRight : Alignment.centerLeft,
    child: Container(
      padding: EdgeInsets.symmetric(vertical: 10, horizontal: 15),
      decoration: BoxDecoration(
        color: isCurrentUser
            ? const Color.fromARGB(255, 68, 129, 235)
            : Colors.grey[800],
        borderRadius: BorderRadius.circular(25),
      ),
      child: ConstrainedBox(
        constraints: BoxConstraints(
          maxWidth: MediaQuery.of(context).size.width * 0.7,
        ),
        child: Text(
          message.text,
          style: TextStyle(
            color: Colors.white,
            fontSize: messageFontSize,
            height: 1.4,
          ),
          overflow: TextOverflow.visible,
          softWrap: true,
          maxLines: null,
          textAlign: TextAlign.left,
        ),
      
                      ),
                    ),
                  ),
                );
              },
            ),
          ),

You can fix that by adding this property to your Text widget:

textWidthBasis: TextWidthBasis.longestLine

Your code should look something like this:

Text(
          message.text,
          style: TextStyle(
            color: Colors.white,
            fontSize: messageFontSize,
            height: 1.4,
          ),
          overflow: TextOverflow.visible,
          softWrap: true,
          maxLines: null,
          textAlign: TextAlign.left,
          textWidthBasis: TextWidthBasis.longestLine,
        )

So instead of having this:

It will look like this:

Hope this help!

 minWidth: MediaQuery.of(context).size.width * 0.5,
 maxWidth: MediaQuery.of(context).size.width * 0.7,
//use minwidth looks great for the text of short messages

because you are using ConstrainedBox just to limited the mxaWidth , but minwidth or intrinsic behavior ,

solution simply is using IntrinsicWidth insinde Align or Contianier like for exaple :

return Padding(
  padding: EdgeInsets.only(
    top: sameUserAsNext ? 4.0 : 10.0,
    bottom: 4.0,
    left: 10.0,
    right: 10.0,
  ),
  child: Align(
    alignment: isCurrentUser ? Alignment.centerRight : Alignment.centerLeft,
    child: ConstrainedBox(
      constraints: BoxConstraints(
        maxWidth: MediaQuery.of(context).size.width * 0.7,
        minWidth: MediaQuery.of(context).size.width * 0.1, 
      ),
      child: Container(
        padding: EdgeInsets.symmetric(vertical: 10, horizontal: 15),
        decoration: BoxDecoration(
          color: isCurrentUser
              ? const Color.fromARGB(255, 68, 129, 235)
              : Colors.grey[800],
          borderRadius: BorderRadius.circular(25),
        ),
        child: Text(
          message.text,
          style: TextStyle(
            color: Colors.white,
            fontSize: messageFontSize,
            height: 1.4,
          ),
          softWrap: true,
          overflow: TextOverflow.visible,
        ),
      ),
    ),
  ),
);

tell me if that works well .
