AA
Really problem is this🤦🏻♂️
AA
Ohh thank you do much
DS
build is for build. not for calling api or save smth on sdcard, etc...
use initState and some async for this

Then have not i use future builder?
DS
ex (using setState):
String text;
fetchPhoto() async {
text = await loadStringFromSite();
setState((){});
}
initState(){
fetchPhoto();
}
build(){
...
Text(text ?? "placeholder"),
...
}
}
