Closed nimr77 closed 3 years ago

nimr77 commented 3 years ago

this is my flutter doctor

Doctor summary (to see all details, run flutter doctor -v): [✓] Flutter (Channel stable, 2.0.5, on Linux, locale en_US.UTF-8) [✓] Android toolchain - develop for Android devices (Android SDK version 30.0.3) [✓] Chrome - develop for the web and everything is working well, but the plugin adds about 18 mega to the app release size, and crush it when we open it.

Yes, it's on android level 23, I have loved your plugin so much, but the size and the crash blocked me

@nimr77 it seems to be a known issue caused by Flutter release build. I've solved the issue by disabling minifyEnabled and shrinkResources in build.gradle：

buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
            minifyEnabled false
            shrinkResources false
        }
    }

You can then build the apk with the following command to shrink the apk size:

flutter build apk --release --split-per-abi

So in order to use the plug-in I must disable the minify and the shrink resources, and what about deploying the result shrinks, I have ended up using another plug-in.

@nimr77 I've found the perfect workaround. You just need to add -keep class com.dynamsoft.dbr.** { *; } to proguard-rules.pro, and edit the build.gradle file:

buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

@nimr77 I've updated the repo and pushed a new version to pub.dev. I think I can close the issue now. Thanks for your feedback.
