i have mp3 file binary stream and i need convert to PCM format to play realtime.
Can you add decode feature?

flutter run
Lexical or Preprocessor Issue (Xcode): 'util.h' file not found

经过详细的测试发现：
录制的pcm流是正常的，但是经过mp3编码后会出现哒哒的声音。
如果把最初的2800帧流截取掉，就能消除哒哒的杂音。
但是上述的方法会出现新的问题，当播放器初次播放的时候，播放到一半左右的位置就自动暂停了，下一次播放就是正常播放到结束。
上述问题只在iOS环境下出现，Android环境正常。

In my application, I am converting a WAV file to MP3 similarly to the example, but I have noticed a very high growth in memory consumption every time the encoder is initialized.
My app without performing any action consumes 19MB of memory, but every time I initialize the encoder, this memory increases 20MB more.
That is, if I start with a constant consumption of 19MB, when I use the encoder, it increases to 35MB, then 54MB and so on.
Even if I call the garbage collector, the resources that occupy the memory are not released.

Usage:

var encoder = LameMp3Encoder(); //only this line causes the increase in consumption
    IOSink? sink;
      final String outputFilePath = '$defaultPath/$fileName.mp3';
      debugPrint(outputFilePath);

      final wav = await compute(Wav.readFile, inputFile.path);
      wav.toMono();

      final File f = File(outputFilePath);
      sink = f.openWrite();

      encoder = LameMp3Encoder(
          sampleRate: wav.samplesPerSecond,
          numChannels: wav.channels.length,
          bitRate: 30);

      final left = wav.channels[0];
      Float64List? right;
      if (wav.channels.length > 1) {
        right = wav.channels[1];
      }

      //Write file
      for (int i = 0; i < left.length; i += wav.samplesPerSecond) {
        final int endIndex = i + wav.samplesPerSecond;
        final mp3Frame = await encoder.encodeDouble(
          leftChannel:
              left.sublist(i, endIndex < left.length ? endIndex : left.length),
          rightChannel: right?.sublist(
              i, endIndex < right.length ? endIndex : right.length),
        );
        sink.add(mp3Frame);
      }
      sink.add(await encoder.flush());
      await inputFile.delete();
      debugPrint("Finished");
      readyAudioController.sink.add(true);
      recorder.closeRecorder();
      return true;

When adding the library as a dependency I get:

A problem occurred configuring project ':flutter_lame'.
Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
Namespace not specified. Specify a namespace in the module's build file: /Users/[username]/.pub-cache/hosted/pub.dev/flutter_lame-1.0.2/android/build.gradle. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.
