Flutter iOS构建失败：Framework 'Toast'未找到

Android端可正常构建输出，但iOS端构建失败，初始报错信息如下：

Error (Xcode): Framework 'Toast' not found
Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation)
Encountered error while building for device.
Process finished with exit code 1

本人对Xcode和iOS开发不熟悉，已尝试以下修复方案，且每次修改后均清理重建确保生效：

• 清理并重建项目
• 删除iOS的Pods目录及Podfile.lock文件
• 删除Xcode派生数据
• 解除Pods集成后重新配置
• 确认Framework Search Paths包含$(inherited)

按照建议手动在Podfile中添加pod 'Toast'后，出现新的报错：

Error (Xcode): Framework 'sqflite' not found
Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation)
Encountered error while building for device.
Process finished with exit code 1

所有Flutter插件均已更新至最新版本，目前无法确定问题根源，恳请提供解决建议。
