Trying to run the Example in the Readme #264

leoheck · 2022-07-17T02:45:50Z

Hi, I am experimenting your setup, trying the example of the gallery that is on Readme.

This one

It seems it is not working. Since I don't know flutter, I cannot easily fix it, yet. Could you give me an idea on how to solve this?

➜  flutter_gallery git:(5da082d) git checkout 5da082d

HEAD is now at 5da082d null safety : Migrated standalone files to null safety (#586)
➜  flutter_gallery git:(5da082d) flutter build bundle

Running "flutter pub get" in flutter_gallery...                  2,619ms

💪 Building with sound null safety 💪

Oh, flutter pub upgrade has solved the Errors, it was left with 2 warnings only.

How do I make sure which version of things I have? Or better, how do I fix it? I am new new to this flutter-world

leoheck · 2022-07-17T03:12:30Z

So, on my computer (Ubuntu 22.04) I have this

I am using the latest engine binaries

    update binaries for flutter 3.0.4

It looks like they are not the same version as my flutter which is 3.0.5

leoheck · 2022-07-17T04:47:21Z

Nice, could clone the flutter repo, select the tag 3.0.4 and use it. It worked!

ardera · 2022-07-18T20:47:02Z

Yeah, just uploaded the 3.0.5 engine binaries. Should really setup CI for this

leoheck · 2022-07-18T21:03:03Z

Ah, indeed. That would be awesome.

leoheck · 2022-07-18T21:03:45Z

By the way, this flutter-pi is pretty awesome. Thanks for making this project and for making it available.
