[muhammadmubashir24]

i am facing this issue if i run fvm flutter run

and fvm flutter doctor showing

but andriod studio install i run flutter doctor without fvm its all ok what can i do

[leoafarias]

@muhammadmubashir24, are you running fvm flutter run within the Android Studio terminal? Could you run it similarly to how you did with flutter doctor, and vice versa, to check for any environment issues?

[muhammadmubashir24]

yes if i run in specific projec within the android studio terminal its showing above error i already attached but if i run this outside cmd terminal outside the project so no issue found showed

The way I found to fix this is to first use HTTP/1.1 and then increase the post buffer size.

Use HTTPS/1.1

git config --global http.version HTTP/1.1

And then increase the buffer size using

git config --global http.postBuffer 2038500000

However, the trick is to increase the buffer based on the bytes mentioned in the error message that says it cannot download. For example, the git error looks like this:

    Receiving objects:   5% (28560/532810), 19.44 MiB | 336.00 KiB/s
    error: RPC failed; curl 18 transfer closed with outstanding read data remaining
    error: 5319 bytes of body are still expected
    fetch-pack: unexpected disconnect while reading sideband packet
    fatal: early EOF
    fatal: fetch-pack: invalid index-pack output

Here, the line error: 5319 bytes of body are still expected mentions 5319 bytes. So, keep increasing the buffer size until it gets small enough, i.e., zero, to get this working.

git config --global http.postBuffer {additionalbytes}

thanks it worked

I don't even use this project, but I had the same issue and ended up here. Posting what worked for me somewhere because it's probably useful anyway: the Starbucks WiFi was the issue.
