在颤抖中使用if语句和图标

Question

i have an if statement and I want to set two conditions inside it as the following code shows:

if (subtitle !="you are currently not signed in" && Icon==Icons.bookmark_border) {.....}

but I cant do so since it is giving the following error "equality operator == invocation with reference of unrelated types".

Any idea about how to implement this

Answer 1

In your case Icon is a type .
You cannot compare a type with an object ( Icons.bookmark_border is an object of type IconData ).

Maybe you have a typo in your code and wanted to write lower case "icon" .
If not, you probably firstly need to fetch your icon.

Answer 2

Can you please post the Code where you get your Icon that you want to compare?
Like @creativecreatorormaybenot already said you're trying to compare the Icon type with an object of type IconData, you need to compare an iconData object to another iconData object .

Note: IconData is just the class for one of the icons in Icons.[something]
Icon is a flutter widget, used to display Icons for the user.

So

final IconData icon = Icons.ac_unit; //icon is just the name of the Object. IconData would be the type.

//replace icon with the object (of type IconData) you get from your FutureBuilder
if (subtitle !="you are currently not signed in" && icon==Icons.bookmark_border) {.....}

should work.
