QUESTION
I am working with a flutter app. I am trying to display data from a json.
I am stuck on the following error:
LateInitializationError: Field 'data' has not been initialized error
My main.dart file is as follows:
...ANSWER
Answered 2022-Apr-10 at 16:37late List data;
should change to List? data;
. If something is non-nullable but late
, it relies on the developer to make sure this variable is initialized before it is used.
Since it's used in the build
method, in data == null ? 0 : data.length;
, it will throw an error.
Changing it to a nullable List?
fixes this.

Here is my code (the json is in the code):
...ANSWER
Answered 2022-Apr-09 at 21:23a few issues with the code.
- the
restaurant
variable you provided doesnt need to be "jsonified", you can use it as is. - the path
/restaurant/city
is supposed to have thecity
as a variable from the user, to achieve that you need to declare the decorator as below. Also now the "city" is argument to the method too:
QUESTION
I have a problem with datetime-local picker in HTML5. I want to clear the datetime with the clear button, but this is not possible because the "required" function inside the input will not allow. I will let a piece of code to see the differences. One is with required and one without required. Do you know how to keep the "required" and also clear the input from ex: "15/03/2022 00:00 AM" to mm/dd/yyyy --:-- --. Thank you.
...ANSWER
Answered 2022-Mar-15 at 14:42The attribute required is responsible for whether the reset button is shown or not. If required is set, you must solve the reset programmatically. You do this for the type datetime-local
with yourDateElement.valueAsDate = null
.
QUESTION
Basically, I have this flex container named question__container, inside of which are my flex-items. I want to align the question, the input and the button to the left within that container. Tried
- wrapping the elements inside another container and set align-items to left
- tried flex-start within that container, overflows.
Please guide.
...ANSWER
Answered 2022-Mar-03 at 07:47You will need to add align-items: flex-start;
instead of center on your .question__container
to do that and remove margin: 0 auto
on .question__container input.text-answer
.
Edit:
You can add this to those elements
QUESTION
As crazy as it sounds, it's been a while since I worked with CSS and HTML. I am trying to recreate the design featured below.
However, how can I format the form that would allow me to split the current form across two columns? I am using a div to group each column with specifiying width and float in CSS, but does not seem to be working.
Any thoughts?

QUESTION
I've tried everything, from setting the body to a specific 100VH, to give Absolute and Relative statement, some of these would do some "fix" but bring other problems. If i set a 100vh to the body the footer will stay at the bottom but of the page (visible of course as it should as it is sticky) but when you scroll all the way down on some pages there will be a blank space below the footer.
here is the code:
...ANSWER
Answered 2022-Jan-11 at 16:46Since you know the height of your footer, you can extend your content element, to be a minimum of 100vh, minus the height of the footer. I'm assuming it's your section element?
