The headlines are all in that list, issue is the indent of your print, it should be outside the loop and print the list only ones.

If I understand your question correctly, you're trying to access _ButtonLoginState from another class/file. However, in Dart, classes, members, variables, etc. that begin with an underline ("_") are considered private. You can't access them from a different file (except in some special situations with libraries).

To solve this, you can change the name of the class to ButtonLoginState and it should work.

EDIT: In response to more info:

You don't seem to have fully understood the concepts of State in a StatefulWidget. I would strongly recommend taking a good look through the Flutter guide on the subject.

There are many different ways of managing state and what I am going to explain is almost definitely not the best option most of the time (this was the introductory approach some time ago, but I can't even find the example anymore), however, it does work. For a more general option, I recommend Provider.

In your case, the problem starts with this: Text(InputEmailState.getUsername). You're not calling InputEmailState.getUsername, you're simply passing a reference to it. You need to include parentheses to actually call it - InputEmailState.getUsername().

However, this isn't the whole issue. You're trying to access this function using the name of the class, which means you're trying to use it as a static method. However, its an instance method (ie: you need a specific instance of the class to access it. This is the state I was talking about.

To simply get access to the state object of a specific widget, you can use a Key (generally a GlobalKey). You can define this in a parent widget, for example, and pass it as the key parameter of your InputEmail widget and keep a reference in the parent class. Then, to get the username, you can call .currentState.getUsername() which will return the instance value. The exact implementation varies, and I don't have your code to know how it should be implemented.

As I say, this isn't really the recommended approach anymore. I strongly recommend getting to grips with the state concept, then it should be obvious what the best approach is.

I've mad you an example, you can add box-shadow to the header and the footer and in that way you can create a blur effect between your elements.

Root cause: You got this behavior in the landscape mode because the height of LinearLayout is larger than the screen's height, so you just see a portion of the LinearLayout. You can reduce the height to see the rounded corner, for example.

Change this:

In the very first iteration, when k = 0, the condition k - 1 >= 0 will evaluate to false, 0 - 1 is not >= 0, the same happens with l, as a result count will be 0 and a division by 0 is performed.

Also, count should be an integer value, preferably unsigned. To avoid integer division rounding problems resulting from this change, you can later cast sumRedor count to float, i.e:

As mentioned before, it is highly recommended to load the JSON instead of using REGEX. But if you must use REGEX:

Using regex101 I have r".recipeIngredient(.*)" which is matching just "recipeIngredient": [

You can use the re.DOTALL flag if you want . to including newlines.

You need to remove height from container.

Why you can't to add a container?

you can add some style:
