Hi @shubhamsinha2009
Thank you for opening this issue.
Could you provide more information about your problem?

You can paste the text of flutter doctor -v here.

And do you know which device had this problem and which Android version was used?

Also facing this issue. Project builds but AlhPdfView is not visible on the screen.

Really hoping you can fix this as this is possible the best pdf package out there at the moment.

Potential issue

I've found this in the onError:

java.lang.UnsatisfiedLinkError: No implementation found for long d.e.a.c.o(int, java.lang.String) (tried Java_d_e_a_c_o and Java_d_e_a_c_o__ILjava_lang_String_2)

Package

alh_pdf_view: ^0.3.0

Flutter doctor -v

I have found a fix

Create a file called proguard-rules.pro in android/app/ directory.

Add this to the file

-keepclasseswithmembernames,includedescriptorclasses class * {
    native <methods>;
}

in the app level build.gradle (android/app/build.gradle) add this to your release build type

            minifyEnabled true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

e.g.

    buildTypes {
        release {
            signingConfig signingConfigs.debug
            minifyEnabled true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

Hello @carman247
Thank you for the extra information.
I will try to reproduce this problem and will release a fix asap.

[carman247]

@andreBalh

No problem, unfortunately I'm not sure how to implement this fix in the package, only projects depending on it

[andreBalh]

Yep your suggested solution would work and I could implement this for the example project but it would be better if you don't have to add proguard just to fix it @carman247

[andreBalh]

I found a solution to fix this problem, I will make a PR and release the fix @carman247 @shubhamsinha2009

[andreBalh]

I am closing this issue, fix will be released in v.0.3.1
