[image_picker] crash when start

[riyanWi]

I have a trouble when I am using image_picker 0.6.3, my app always crash when developing but can run when debug.
This is crash log

Does this reproduce for you in the image_picker example app? If not, can you provide a minimum reproduction so that this can be debugged/triaged?

Confirmed. Works when devving, but when doing flutter build apk and running that, I get the same errors.

I fixed this by disabling tree shaking with minifyEnabled and shrinkCode. It is simply bad and unreliable.

If anyone ever faces issues that pop up only during release build, try that.

no, when I tried on example app it's work.
this is my code

  Future getImageCamera() async {
    var img = await ImagePicker.pickImage(
        source: ImageSource.camera, imageQuality: 60);
    setState(() {
      image = img;
    });
  }

  Future getImageGalery() async {
    var img = await ImagePicker.pickImage(
        source: ImageSource.gallery, imageQuality: 60);
    setState(() {
      image = img;
    });
  }

But when I remove that code and just import package image_picker my app still crash.

Can you give more details on how to do this?

[dnfield]

I believe you can just pass --no-shrink to the Flutter tool to disable shrinking.

We shouldn't require you to disable shrinking for this plugin.
/cc @blasten - did we miss this one when evaluating proguard/r8 rules?
