Recording calls in a Flutter app is a challenging task due to privacy regulations and platform-specific restrictions. Both Android and iOS impose limitations to prevent unauthorized call recording, and any attempt to bypass these restrictions may violate local laws or app store policies.
Use Third-Party Services Integrate a VoIP (Voice over IP) service like Twilio. These services handle legal compliance and technical limitations.
Microphone-Based Recording Record audio using the app's microphone, but this won’t capture the other side of the conversation. It's not an ideal or legal approach.
Ensure compliance with privacy and legal regulations. These are the options based on my experience, though there may be many others.
