flutter why is this fired twice?
1
I have this simple code.
The method getPrint returns 'a', 'b', 'c' twice.
Total six String are returned.
Am I doing something wrong?
List<String> li;
Future<List<String>> getList() async
return ['a', 'b', 'c'];
void getPrint()
for (String l in li)
print(l);
void _init() async
li = await getList();
getPrint();
@override
void initState()
_init();
super.initState();

I've run this several times both as simple dart files and in a flutter widget and I only get the print once every time.

really? In my case every time I tapped bottom navigation bar, print twice. Is this about bottom navigation perhaps then?

Can you show the actual widget you use? You're likely doing something wrong. I'd guess you're using FutureBuilder and callinitfrom build

Sorry it was about bottom navigation bar I called setState to change background color of bottom navigation and that's the reason. Thank you for your help guys!
