Flutter how do I remove unwanted padding from Text widget?

I have a Text widget and not sure why it seems to just have padding at the top and bottom even though I didn't set any in the code. This is from the default Flutter app, I just modified the font size.

  body: Center(
    child: Column(
      children: <Widget>[
        Text(
          '0:00.00',
          style: TextStyle(fontSize: 76),
        ),
      ],
    ),
  ),

This is a screenshot of the highlighted Text widget in Android Studio. There's really nothing else adding any padding so I don't know why it's there.

Sometimes you get this in CSS where there is padding even though none was set but you can remove it simply with padding: 0 but I don't see how to do it here since I can't find a padding option for the Text widget.

EDIT: The amount of padding changes with the size of the font. It seems to always contain a certain amount of padding, like a html H1 tag.

I found the solution myself in the end. It can be positioned using Stack and Row widgets. I found Row works better than using Positioned as the text can be centred using the Row widgets.

  body: Stack(
    children: <Widget>[
      Row(
        mainAxisAlignment: MainAxisAlignment.center,
        children: <Widget>[
          Text(
            '0:00.00',
            style: TextStyle(fontSize: 76),
          ),
        ],
      ),
      Padding(
        padding: EdgeInsets.only(top: 56.0),
        child: Row(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text(
              'Coke',
              style: TextStyle(fontSize: 76),
            ),
          ],
        ),
      ),
    ],
  )

It kind of works like the negative padding in CSS but actually it's the padding that moves the bottom text down rather than up since otherwise they occupy the same space.
