TextOverflow in Column using Flutter

Question

I have a Text widget inside Column which is inside Padding. And this Padding is children of Row which is the child of another Padding.

So the structure would be: Container > Padding > Row > Padding > Column > Text.

I tried to handle text overflow, but all of the overflow do not work. I tried to put the Container inside Expanded widget, but the view totally gone instead.

Here is my code :

Container(
      decoration: constHomeBoxDecorationStyle,
      child: Padding(
        padding: const EdgeInsets.symmetric(
          vertical: 8.0,
          horizontal: 16.0,
        ),
        child: Row(
          children: [
            SvgPicture.asset(
              "assets/images/avatar.svg",
              width: 48.0,
              height: 48.0,
            ),
            Padding(
              padding: const EdgeInsets.symmetric(horizontal: 16.0),
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [
                  Text(
                    name,
                    style: TextStyle(
                      fontSize: 32.0,
                      fontWeight: FontWeight.w700,
                    ),
                  ),
                  Text(
                    name,
                    overflow: TextOverflow.clip,
                    maxLines: 1,
                    softWrap: false,
                    style: TextStyle(
                      fontSize: 24.0,
                    ),
                  ),
                ],
              ),
            ),
          ],
        ),
      ),
    );

In the same page, I tried to build another Text Widget to test the overflow.

The structure is like this: SingleChildScrollView > Column > Padding > Column > Text.

This one works perfectly fine (with same Text widget code from above.

Any idea why the first one does not work?

Edit 2: The Answer (based on Piyush Dubey's answer)

Container(
      decoration: constHomeBoxDecorationStyle,
      padding: EdgeInsets.symmetric(vertical: 8.0),
      child: ListTile(
        leading: SvgPicture.asset(
          "assets/images/avatar.svg",
          width: 48.0,
          height: 48.0,
        ),
        title: Text(
          name,
          maxLines: 1,
          style: TextStyle(
            fontSize: 28.0,
            fontWeight: FontWeight.w700,
          ),
        ),
        subtitle: Text(
          password,
          style: TextStyle(
            fontSize: 20.0,
          ),
        ),
      ),
    )

Actually Text widget wrap themselves as the biggest parent, In the first case the Row widget has the max width/ Flutter assume that row has max width but row has limitation of context which makes it to overflow — Piyush Dubey

So do you have any workaround with that? Expanded and Flexible do not work too — wiryadev

Can you post your end output in that case we can help with the accurate widget tree — Piyush Dubey

use ListTile Widget instead. It will be much efficient and easy for you to achieve — Piyush Dubey

You can use ListTile widget to achieve that,

         ListTile(
            leading: Icon(Icons.add),
            title: Text('GFG title',textScaleFactor: 1.5,),
            trailing: Icon(Icons.done),
            subtitle: Text('This is subtitle'),
            selected: true,
            onTap: () {
              setState(() {
                txt='List Tile pressed';
              });
            },
          ),

You have to use Expanded widget as the parent of the Padding widget in the Row widget as shown below:

Container(
  decoration: constHomeBoxDecorationStyle,
    padding: const EdgeInsets.symmetric( // <----- REMOVED PADDING WIDGET AS CONTAINER ALREADY HAS PADDING PROPERTY
      vertical: 8.0,
      horizontal: 16.0,
    ),
    child: Row(
      children: [
        SvgPicture.asset(
          "assets/images/avatar.svg",
          width: 48.0,
          height: 48.0,
        ),
        Expanded(child: Padding( // <---------- HERE
          padding: const EdgeInsets.symmetric(horizontal: 16.0),
          child: Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: [
              Text(
                name,
                style: TextStyle(
                  fontSize: 32.0,
                  fontWeight: FontWeight.w700,
                ),
              ),
              Text(
                name,
                overflow: TextOverflow.clip,
                maxLines: 1,
                softWrap: false,
                style: TextStyle(
                  fontSize: 24.0,
                ),
              ),
            ],
          ),
        ),),
      ],
    ),
);

Also, there is no need to create Padding widget as the child of your Container widget as Container already has padding property.
