It is recommended to use printLog=false when releasing your app.

Q. How can I apply different settings for different environments?

A. You can use the profile parameter in Netfunnel.instance.initialize() to apply environment-specific settings.

// Production environment (Tokyo)
await Netfunnel.instance.initialize(profile: 'prod_tokyo', ...);
// Production environment (US East)
await Netfunnel.instance.initialize(profile: 'prod_us_east', ...);

Q. I am encountering errors when using HTTP communication.

A. NetFUNNEL Flutter Agent recommends using HTTPS communication by default. If you need to use HTTP, you can allow HTTP traffic through platform-specific settings.
