Text in tutorial doesn't scroll

[MarcoFiorentino]

In one of mine TargetFocus the text is too long so I'd like to make it scrollable.

The TargetFocus is this:

TargetFocus(
  identify: "BardPublicType",
  keyTarget: keyTargets["chooseBardPublicTypeKey"],
  enableOverlayTab: true,
  enableTargetTab: true,
  shape: ShapeLightFocus.RRect,
  radius: 5.0,
  contents: [
    TargetContent(
      child: Column(
        mainAxisSize: MainAxisSize.min,
        crossAxisAlignment: CrossAxisAlignment.start,
        children: <Widget>[
          Padding(
            padding: const EdgeInsets.only(top: 50.0),
            child: Text(
              translate("tutorial.bard_public_column_title"),
              style: const TextStyle(fontWeight: FontWeight.bold, color: Colors.white, fontSize: 20.0),
            ),
          ),
          Padding(
            padding: const EdgeInsets.only(top: 10.0),
            child: Text(
              translate("tutorial.choose_bard_public"),
              style: const TextStyle(color: Colors.white, fontSize: 18.0),
            ),
          ),
        ],
      ),
    ),
  ],
),

The last text is the one too long.
I tried to put it in a SingleChildScrollWiew but it didn't work.
I tried to put even the Padding or the whole column in a SingleChildScrollView but this doesn't work either.

Any idea to how to make it?
