Printing for Debugging

You might be used to println! macro in Rust. However, using that macro isn’t a very good idea in our apps made with Flutter and Rust because stdout stream cannot be seen on the web and mobile emulators.

When writing Rust code in the hub crate, you can simply print your debug message with the debug_print! macro provided by this framework like below. Once you use this macro, Flutter will take care of the rest.

Rust

use rinf::debug_print;
debug_print!("My object is {:?}", my_object);

debug_print! only writes the code in debug mode, resulting in a smaller and cleaner release binary.
