Flutter speech_to_text：^ 2.2.0包不收听-初始化问题？
问题描述 投票：-1回答：1
要开始使用软件包，我已经尝试了开发人员提供的代码。我在Windows 7 64位计算机上，使用了nexus 4，现在将nexus 5x虚拟机与android 5以及现在与Android Q一起使用。除此之外，还有一部真正的带有android 7.0的手机。手机的车载文本到语音功能可完美运行。在每种配置中，除非我单击“初始化”，否则界面实际上似乎没有响应-除了在Android Studio的“运行”窗口中之外，该应用程序没有任何反应。这是读数：

Android Studio，flutter和node已安装3天，我已经使用-v运行了flutter Doctor，并且没有使用该参数。以前，某些许可证未签名，现在已排序。

我已经通过向yaml添加依赖项并导入了pub来导入该软件包，并且用尽了更多的构想。请帮忙。谢谢。

使用Speech_to_text插件的应用程序需要用户许可。您需要在Info.plist文件中添加iOS所需的密钥。对于Android，您需要在AndroidManifest.xml中添加录音音频权限。
以下是包装说明：https://pub.dev/packages/speech_to_text向下滚动到“权限”。在那里，您可以看到如何添加所有所说的内容。
