You need to install the component called "Windows 10 SDK (10.0.17763.0)"

Running the x64 Native Tools Command Prompt for VS 2019 cmd prompt makes the various MSVC tools available on the command line, e.g. msbuild, but does not appease flutter doctor.

Your screenshot shows the required SDK version as unselected, so you are missing one of the required components listed by doctor

Apparently in VS 2019 it's now possible to just set the version to "10.0" instead of an exact version, which wasn't possible when I was initially researching this. We may want to require 2019 so that we can switch to that, since this has been, and will continue to be, a pain point.

how do I fix the issue?

Unfortunately there doesn't appear to be a generic component ID for "latest SDK" so even if we set it to 10.0 and required VS 2019 doing the vswhere query would be very messy, and require tool updates for every Windows SDK release.

Then the bug is that flutter doctor says to do two things:

Install the "latest" Windows SDK, which is "10.0.18362.0" right now.
Install ""Windows 10 SDK (10.0.17763.0)".

2 works. #1 does not.

The line about installing the latest goes with the build tools, not the SDK. That's supposed to be clear from formatting but the indentation looks like it's messed up.

We should fix the indentation, and explicitly mention build tools again in that line so that confusion can't happen regardless of indentation.

Closing since the text was improved to help avoid this confusion. #50487 tracks trying to eliminate the need for a specific SDK version entirely which would avoid this common problem.
