UpgradeCard does not show and scroll release notes properly

Problem

I have added upgrader to two different apps. In one app I use UpgradeAlert and in another app I'm using UpgradeCard since that app has a different upgrade flow.

I had earlier problems in getting release notes to show properly and be scrollable, but when upgrading to 7.1.0 I noticed that scrolling of release notes works properly when using UpgradeAlert.

However, UpgradeCard does not seem to work correctly.

Code

I'm using an UpgraderMessages implementation, that looks something like this:

class _CustomUpgraderMessages extends UpgraderMessages {
  @override
  String get title => '<...>';

  @override
  String get body => '<...>';

  @override
  String get buttonTitleUpdate => '<...>';

  ...

  @override
  String get releaseNotes => '<...>';
}

and it is passed something like this:

Upgrader(
      countryCode: '***',
      messages: _CustomUpgraderMessages(),
      debugLogging: kDebugMode,
      durationUntilAlertAgain: Duration.zero,
      showIgnore: false,
      showLater: false,
    )

--EDIT--

Our single Upgrader instance is passed to UpgraderCard like this:

UpgradeCard(margin: EdgeInsets.zero, upgrader: upgrader)

so it should not be a problem of UpgraderCard using any other instance.

Expected behavior

UpgraderCard uses releaseNotes properly from the _CustomUpgraderMessages implementation.
UpgraderCard makes it possible to scroll longer release note texts with not truncation.

Actual behavior

UpgraderCard displays "Release notes" instead of the value from _CustomUpgraderMessages.
UpgraderCard truncates a longer release note texts with "..." and does not make it scrollable.
