Flask version: Black incompatibility

[Phxntxm]

Hello, I want to essentially just ask if there are plans to update Flask to version 2? The reason I ask this is because due to requirements, this library is incompatible with black... a very common python formatter.

Black requires click>=8.0
You require Flask <2
The latest version that matches that, 1.14, requires click<8

With how common black is, I think this a pretty important incompatibility to resolve.
I do notice that dev_requires includes a black version of 19.10b0, however that's a 3 year old prerelease version... I really feel this should be updated.
