Expected output from Trace and from emitObfuscatedFiles options?

I've added the `trace` option to my configuration to help me determine why the output doesn't seem to be transformed at all, but I've not been able to determine where I should see this output. It doesn't appear in my console.

I haven't been able to find any output files anywhere either. Where would one expect to find those?

Thanks for any advice!

检查 `trace` 和 `emitObfuscatedFiles` 配置选项，并确定此 transformer 在哪里报告控制台输出以及写入文件。完成标准是记录 React Native 用户预期的输出位置和行为。
