Help please, I can't seem to run the texture_renderer example cause of uncompatibility with the file_picker packgage, I was trying all different file_picker version from 8.1.2 until 8.1.5

Also, It seems not a problem of opencv_dart, why do you open the issue here rather than file_picker.

P.S., You do not need to use both opencv_dart and opencv_core, just choose one of them, depending on whether you need videoio module.

Sorry my bad for posting this as issues, on another note I forgot to mention that using Imageformat as in imencode(cv.Imageformat.png.cv, img, params) is not working on another example (i forgot which)

[rainyl]

cv.Imageformat was deprecated a long time ago, you can use ".png" directly. cv.imencode(".png", image)

abdelaziz-mahdy has reported this in file_picker, check this:

• Android compile error registrar  miguelpruivo/flutter_file_picker#1643

[fadelfffar]

okidoki thanks for your help, I'm gonna close this issue

[fadelfffar]

Hello, I have use the temporary fix from abdelaziz-mahdy, but get a GNUC_PREFEQ compiler error and a arm64-v8a error from dart cv, any idea why? thanks in advance ;)

[rainyl]

I think you can just use 8.1.4, it works fine for me.

[fadelfffar]

hmmm weird, I already tried that earlier. Does this need Nvidia gpu in anyway?

Nope. Did you use the exact version of 8.1.4? miguelpruivo/flutter_file_picker#1643 (comment)

Also mind that texture_rgba_renderer only supports windows, linux and macos for now, android is not supported.

[fadelfffar]

yes i did, without the ^ on pubspec.yaml, maybe because I run it on android lol, thanks

[rainyl]

All right, kind of weird...
