flutter cognito 插件发布版本

Question

我在 flutter 构建的 task:compileReleaseKotlin 期间遇到了这个错误，问题参考 flutter cognito_plugin 我正在使用命令 flutter 运行 --release with signing key 它一直有效直到它在 task:compileReleaseKotlin 上停止。并显示许多类似的行，这会阻止我的应用程序的所有发布过程并且不知道如何解决；你知道我该如何解决吗？有没有 l

这是/build.gradle

buildscript {

    ext {
        compileSdkVersion = 29                // or higher

    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.3'

allprojects {

您必须配置 proguard。我有同样的问题。

在 android/app/build.gradle 文件的 buildTypes 部分添加以下配置。

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

在 android\app\proguard-rules.pro 创建 proguard-rules.pro 文件并添加以下内容。

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