QUESTION
This is probably caused by something stupid I'm doing or forgetting to do. Below is a full working code example (as of Dec5 2019) for Flutter and an HTTP echo server (httpbin) for reproducing this problem.

when rebuilt, the new widget has a different Future instance than the old one
https://github.com/flutter/flutter/issues/11426#issuecomment-414047398
didUpdateWidget of the FutureBuilder state is being called every time a rebuild is issued. This function checks if the old future object is different from the new one, and if so, refires the FutureBuilder.
To get past this, we can call the Future somewhere other than in the build function.
https://docs.flutter.io/flutter/widgets/FutureBuilder-class.html
The future must have been obtained earlier, e.g. during State.initState, State.didUpdateConfig, or State.didChangeDependencies. It must not be created during the State.build or StatelessWidget.build method call when constructing the FutureBuilder. If the future is created at the same time as the FutureBuilder, then every time the FutureBuilder's parent is rebuilt, the asynchronous task will be restarted.
A general guideline is to assume that every build method could get called every frame, and to treat omitted calls as an optimization.

Install httpdebug
You can use httpdebug like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
