Questions about making a wrapper package in flutter

[Urs Fleisch]

As you can see on the top of https://taglib.org/

TagLib is distributed under the GNU Lesser General Public License
(LGPL) and Mozilla Public License (MPL). Essentially that means that
it may be used in proprietary applications, but if changes are made to
TagLib they must be contributed back to the project. Please review the
licenses if you are considering using TagLib in your project.

So I would say that you can link to TagLib as you like, and you do not
have to change your package's license.

Best regards,
