Hereby including platform exception. To do with proguards

I too have the same error, did you find a solution?

E/flutter: [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: PlatformException(error, Unrecognized suffix for the AWS http client class name b, null)

Ah, nevermind.

Looks like the solution is here: #7

You need to follow the instructions here:

https://stackoverflow.com/questions/35480567/am-getting-error-after-i-created-amazon-coginto-in-android

In short I created a file under '/android/app/proguard-rules.pro' and used all lines starting "-keep" from https://github.com/krschultz/android-proguard-snippets/blob/master/libraries/proguard-aws-2.1.5.pro, then in your 'android/app/build.gradle' you can add:

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

            // Enables code shrinking, obfuscation, and optimization for only
            // your project's release build type.
            minifyEnabled true

            // Enables resource shrinking, which is performed by the
            // Android Gradle plugin.
            shrinkResources true

            // Includes the default ProGuard rules files that are packaged with
            // the Android Gradle plugin. To learn more, go to the section about
            // R8 configuration files.
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }

it works for me

I ran into the same issue. The upload was working in debug however, facing issues with release build. I followed the below steps to resolve it.
You have to configure proguard.

1. Add below config at android/app/build.gradle File inside buildTypes section.

buildTypes {
    release {
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
            multiDexEnabled true
            minifyEnabled true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
            'proguard-rules.pro'
        }
}

2. Create proguard-rules.pro File at android\app\proguard-rules.pro and add below content.

-keep class com.amazonaws.** { *; }
-keep class com.amazon.** { *; }
-keep class com.pycampers.** { *; }
