Limitations while selecting tag
Can anyone please help me how do we limit the selection of tags like I just want to add 3 tags if user going to add more than 3 tags then it will show some error message. When I am trying this I am not able to restrict user while selecting tags more than 3.
in order to find out how many are selected and change items based on it try this
onPressed: (item) {
item.active ? selected++ : selected--;
if (selected == 4 && item.active) {
item.active = false;
selected --;
}
},
when set item.active = false; say "active" can't be setter， because it is final
I hope that when I choose a certain number of labels, then I can’t choose other. How can I achieve them?
@bingweibi that's the same thing I want to ask and @SamadiPour as you mentioned item.active = false but it can't be possible because it is mentioned final in plugin if I changed that code in plugin and remove final from it still it is not changing the status of active item to inactive
As said Item class has this field active which is final else we can change it's value even the user press on it to limit selecting i'm having the same issue
