It is working completely fine in debug build, but in release build it's not opening.

Did you find any solution for this?

[abdulmominsakib]

I found a solution for it. This is an issue of the image_picker itself, not the image_cropper. You have to downgrade the gradle version for it. classpath 'com.android.tools.build:gradle:3.6.3'

try to update proguard-rules.pro

proguard-rules.pro file

-keep class io.flutter.plugin.editing.** { *; }
-keep class androidx.lifecycle.DefaultLifecycleObserver
-dontwarn com.yalantis.ucrop**
-keep class com.yalantis.ucrop** { *; }
-keep interface com.yalantis.ucrop** { *; }

build.gradle file

    buildTypes {
        release {
            shrinkResources false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
        }
    }

same here when I use the camera to get a picture it works but not with image picking from the gallery.

image_cropper: ^1.4.0
image_picker: ^0.7.4

W/View    (31661): requestLayout() improperly called by androidx.appcompat.widget.AppCompatTextView{d8f7c1c V.ED..... ......ID 497,26-582,72 #7f0700c0 app:id/text_view_scale} during layout: running second layout pass
I/zygote  (31661): JIT allocated 56KB for compiled code of void android.view.View.<init>(android.content.Context, android.util.AttributeSet, int, int)

getting this in debug mode is this normal
