dart - Flutter how do I remove unwanted padding from Text widget?

Question

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.

There are reasons why the Text widget has this "padding". Take in consideration the next example:

Text(
  '123 gyó',
  style: TextStyle(
    fontSize: 40.0,
  ),
),

As we can see, using another characters like the letters g and y and an uppercase O with an accent marker, shows us that there's no padding on the Text widget really.

Fonts have ascenders and descenders on some characters, and there's also en ascent line for special characters like the accent marker. That's why numbers are centered in the middle. That's not padding on Flutter side, but typography design(?). Maybe you could find a way to sort your issue, by looking for a font without ascenders and descenders.

Conclusion: if you want to select the Text widget with the Flutter inspector, and see no space around some characters, that is not possible.
