Suggest a fix

Update the dependenies in the pubspec.yaml to a newer version, and slightly adjust the way URI’s are handled by the API client. I have a PR coming in shortly for this.

I opened the PR. It’s my first time contributing to an open-source project, so if I’ve made a meal of it just let me know 😊

@lewcianci Thank you for you work on the dependencies! Unfortunately I have not seen your PR earlier and it looks like we have now settled with #9392. If you mention the Dart technical committee in your next PR and/or issue, we will get notified directly. It would be much appreciated if you can review and possibly test #9392 to see if it meets your requirements.
