using if statements and icons in flutter

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

Solution

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.

what is the value of "Icon" var ?

Use IconData instead of Icon. Also what is your variable here that you are trying to compare to Icons.bookmark_border?
