using if statements and icons in flutter



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





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?

In your case Icon is a type.

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


Icon


Icons.bookmark_border


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.





yes my icon is in a widget ubove this if statement that returns icons, ineed to ftch it, how can i do this.

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.


Icons.[something]



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.





Thanks I will try it out.

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
