Cannot record in Wav format on Safari browser

[elios-cama]

Package version
record: ^5.1.2

Environment

• OS: macOS
• Browser : Safari

Describe the bug
When i record an audio on an Apple device (iPhone or Mac), with the Wav encoder, the result in the blob is only 44B in size. The data only contains 'RIFF$WAVEfmt D-+data'.
The recording process works well and I can fetch the data in bytes on Chrome.

Record configuration :
RecordConfig(
encoder: AudioEncoder.wav,
bitRate: bitRate ?? kBitRate, // here 128000
sampleRate: sampleRate ?? kSampleRate, // here : 44100
),

To Reproduce
Launch a simple record on a flutter web project, and try to read the content from the blob url data.
