如何解决Flutter构建时':rive_common:buildCMakeDebug[arm64-v8a]'任务失败问题

构建Flutter应用时遇到以下编译错误，核心问题是指针转换为更小的uintptr_t类型时丢失信息，导致C++编译失败，进而触发Gradle任务执行异常：

FAILURE: Build failed with an exception.

可能的解决方法 #

1. 更新rive_common包 #

当前使用的rive_common版本为0.2.7，该版本存在已知的编译兼容性问题。打开项目的pubspec.yaml文件，将依赖的rive或rive_common更新至最新版本：

dependencies:
  rive: ^latest_version # 替换为实际最新版本号

执行flutter pub get更新依赖后重新构建项目。

2. 调整Android NDK版本 #

错误中使用的NDK版本为25.1.8937393，部分旧版C++代码与该版本存在兼容性冲突。尝试切换至更稳定的NDK版本（如23.x或24.x）：

• 打开android/app/build.gradle文件，在android块中指定NDK版本：

android {
    ndkVersion "23.2.8568313" // 替换为兼容的NDK版本
    // 其他配置项...
}

• 若使用Android Studio，可通过SDK Manager安装指定版本的NDK后选择使用。

3. 修改C++编译标准 #

当前编译使用C11，切换至更高版本的C标准（如C++17）可解决类型转换问题：

• 在项目的android/build.gradle中添加全局C++标准配置：

subprojects {
    afterEvaluate { project ->
        if (project.hasProperty('android')) {
            android {
                defaultConfig {
                    externalNativeBuild {
                        cmake {
                            cppFlags "-std=c++17"
                        }
                    }
                }
            }
        }
    }
}
