I just installed flutter SDK on my windows pc and then I ran flutter doctor and I got this.
[✓] Flutter (Channel stable, 3.0.3, on Microsoft Windows [版本 10.0.22000.739], locale zh-TW)
[✗] Visual Studio - develop for Windows

But I already got visual studio 2022 installed with "Desktop development with C++" on my pc.
What I have tried:
Switch the channel to Master
Install visual studio 2019 with "Desktop development with C++"
Restarting the PC
Reinstall visual studio 2022 with "Desktop development with C++"
I was in the same situation as you.
I solved the problem by bringing vswhere up to date.
In my environment, the following paths are affected.
C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe
Here is the URL I used for reference
https://github.com/microsoft/vswhere/releases

When I launch an app to an Android emulator, I get the following two error messages, but the app works fine:
E/SurfaceSyncer( 6710): Failed to find sync for id=0
W/Parcel ( 6710): Expecting binder but got null!
Environment: Windows 11, AMD Ryzen 6000

No errors occur if I instead launch to Chrome.
Any ideas?
Have you installed Visual Studio? This contains the 'Desktop development with C++' which flutter seems to require. (Visual Studio != Visual Studio Code)
I just updated my flutter folder from 2.15 to 3.0. My app runs fine but there's a big problem: when I do CTRL+S, instead of reload my current page to see the changes, it's restarting my whole app, which is extremely annoying. This didn't happen until the upgrade so thought it was a problem of Flutter 3.0. But I downgraded to the version 2.15 and it keeps restarting instead of reloading.
Here's my "flutter doctor":

I also tried running "flutter clean" and "flutter pub get" but it's the same. It says "Performing hot reload" but it actually performs a full restart. I can't work anymore like this.
When I create the new file of the flutter project the first time it's run smoothly and no issues occur, when I start these projects again after some period of time, the Gradle build is stuck and so much ram usage by the OpenJDK binary platform. After some time pc crashed.

That specific error message from doctor means that the vswhere tool is reporting false for the isComplete property. This means there is an issue with your Visual Studio installation (or at least, Microsoft's tooling believes there is).
