Hi @ezechieldef
Can you please reproduce the blank screen with a new project? flutter create mydemo

If the problem persists, Can you please provide your flutter run -d windows -v logs and minimal complete reproducible code sample?
Thank you

We are therefore reluctantly going to close this bug for now.
Please don't hesitate to comment on the bug if you have any more information for us; we will reopen it right away!
Thanks for your contribution.

Could everyone who still has this problem please file a new issue with the exact description of what happens, logs, and the output of flutter doctor -v.
All system setups can be slightly different, so it's always better to open new issues and reference related issues.

I am facing the same issue when app is released and share the Release folder to another machine that does not do development

[richard457]

Note, on the machine that does development the released app work just fine.

Hi !
I ended up concluding that it is missing packages, because some dependencies do not fully integrate the project.

I had to copy my folder containing my flutter SDK to the user PC in the same location for it to work.

ie, I copied my C: \ flutter folder to the same address to the second PC

That solve my problems

I think the flutter team need to address this issue @ezechieldef @iapicca @TahaTesser @pedromassangocode

Let me try this workaround.

@richard457
as it is the issue is not workable
please provide the info requested here

[richard457]

here is a repo to reduce the issue [REPO]https://github.com/yegobox/flutter_windows)

[richard457]

Here is the current status, the build works on the same machine where the build is run, then when I zip the release folder to another machine it does not. @iapicca

@richard457
please provide a minimal reproducible code sample, not a complete app and without 3rd party plugins and packages
together with your flutter doctor -v

In my case, I didn't have this problem with a simple Flutter project.

Only by copying the release folder, the application runs normally.

but with some complex project this is no longer the case, raison why I thought that it is mainly about the dependencies add to the project, which do not always integrate the project correctly.

I could be wrong any time

@ezechieldef
if the issue is caused by 3rd party plugins there's nothing flutter team can do to fix the problem
that why it's important to have a minimal reproducible code sample

[richard457]

Here is a problem, let's say yes it is caused by a third party plugin, but why the build works on the same machine but not to another machine, to me this is inconsistency, and the flutter team should address that or at least show build error instead of passing the build and have the issue when the app is rolled out. @iapicca

@richard457
I think there is some confusion try to address 2 different problems as it were one:

Here is a problem, let's say yes it is caused by a third party plugin, [...]

if that's the case, 100% the issue should NOT be addressed on flutter repo, but on said 3rd party plugin own repo

[...] but why the build works on the same machine but not to another machine, to me this is inconsistency, and the flutter team should address that or at least show build error instead of passing the build and have the issue when the app is rolled out.

this seems a flutter related issue, for it to be workable MUST be reproducible
therefor the information listed below should be provided

please provide a minimal reproducible code sample, [...] without 3rd party plugins and packages
together with your flutter doctor -v

without these there is no reason for the issue to be open

I thought I had the same issue with flutter 2.2.1 on Windows 10 with Android studio 4.2.1.

But it turned out to be the fact that the app was super slow to load up under development mode on my machine. Here by "load up" I mean "syncing files to device windows" as you can observe in Android Studio's console.

The default push-button project took quite a few seconds to load up on my Windows, a lot slower than the macOS version.
It helped to speed it up by building the release app first

flutter run --release -d windows

then run it inside Android Studio. This time it would be a lot faster to load up the dev build.

Hope this helps.
