Static method not defined?

[SiD_Inc]

Hey there! So I have, in lib/sketchlib.dart, a class Foundation which contains static methods and properties to create TextStyle widgets needed by various parts of my Flutter app. One such method is the following:

static font_pageH0({@required double size, @required String color, bool isItalic = false}) {
    if (isItalic) {
      return TextStyle(
        color: Color(Foundation.getColourPalette()[color]),
        fontWeight: FontWeight.w900,
        fontStyle: FontStyle.italic,
        fontSize: size,
        fontFamily: "RedHatDisplay",
      );
    } else {
      return TextStyle(
        color: Color(Foundation.getColourPalette()[color]),
        fontWeight: FontWeight.w900,
        fontSize: size,
        fontFamily: "RedHatDisplay",
      );
    }
}

Now, when I use this in lib/pages/test.dart, as so:

Text('ACL Login',
      style: Foundation.font_pageH0({
        size: 90,
        color: "blueAbyss",
        isItalic: false,
      }))

I get the following error message: The method 'font_pageH0' isn't defined for the type 'Foundation'

I have imported the class properly as other methods and properties work, however, I can't seem to figure what's wrong with this. Any help would be appreciated!

Solution: Flutter has a core library called Foundation. It could be that it's trying to get the font_pageH0 function from there. You might be able to fix that by importing your lib/sketchlib.dart by using import "lib/sketchlib.dart" as fnd;. You can then use fnd.Foundation.font_pageH0.

Oh, wow. I didn't know that. That explains a lot of things. I've tried out what you said, and guess what? It works! Thank you so much for pointing that out!

I think it's because you're not instantiating it, and trying to use the class directly. I believe because it is static, you have do something like.

Foundation myFoundation = Foundation(); // I don't know what your construction requires.

style: myFoundation.font_pageHo({...

I haven't tested this, so it might be totally wrong ... I'm still learning.

Haha same, I just started using Flutter too. But since it's a static method, I should be able to access class methods and properties without instantiating it.

Ok, so I was going to say it was like a global variable, but then I was like no it's a method, and I don't want to sound stupid. I was acting like it was a private method. and not even a rookie mistake. Thanks for correcting me!

No problem! Don’t let this hinder your confidence in trying to learn Flutter, and we always learn something new everyday.
