Stop Dart before pressing a key

Question

Is there a way to stop the Dart process from running before a key is pressed?

It will be something like:

• In the html file:

<input id="nextstep" type="button" value="nextstep" /> 

• In the dart file:

 void main() { while(true) { // Do something here to pause the loop // until the nextstep button is pressed } } 

Answer 1

You can simply add a keyPress listener to your input to start some additional processing.

 void main() { final input = querySelector("#nextstep"); input.onKeyPress.listen((e){ nextProcessingStep(); }); }
