I worked with flutter for almost a year and since it wasn't production-ready for web development I needed to switch to react.
To render object conditionally inside my build method I had to put an if-else statement rendering my custom widget if the condition was met or a random empty container in the other case.
@override
Widget build(BuildContext context) {
return Container(
child: condition == true
? new MyCustomWidget()
: new Container() //Random empty container to fill the else statement
)
)
Even if this doesn't cause any rendering problem, it's still can be ambiguous for someone reading the code. After working with react I saw that it provides a way to display only the if block using the following notation:
<div>
{condition == true && <MyCustomReactComponent/>} //this block is displayed only if the condition is met
</div>
I was guessing if flutter has a way to do something similar.
