Describe the problem

In the following example:
FutureBuilder(
future: AFutureFunctionCall(),
builder: (context, snapshot) { ... }
)
where lints have discarded_futures: true
Error:
Asynchronous function invoked in a non-'async' function. Try converting the enclosing function to be 'async' and then 'await' the future.

and then we have to use
FutureBuilder(
// ignore: discarded_futures
future: AFutureFunctionCall(),

while this is not really expected. The original error does not seem to be right.

Expected fix

The warning is not wrong
