I am using a riverpod provider class to handle picking of image from gallery. However, once an image is picked, I get the error: PlatformException(multiple_request, Cancelled by a second request null, null). Not sure where a second request is coming from. More importantly, no image is applied to my placeholder (CircleAvartar) due to this unknown cancellation. Here are the two dart files in question and thanks for the help.

I've written and optimized a Shiny app, and now I'm struggling with the IT section of the organization where I work to have it published on their servers. Currently, they are claiming that the app is not W3C compliant, which is true, according to the W3C validator.

The errors I'm trying to solve, with no success, are:

• Bad value “complementary” for attribute “role” on element “form”.

• The value of the “for” attribute of the “label” element must be the ID of a non-hidden form control.

Such errors can be seen also in very minimal shiny apps, like:

I've written code for uploading a file along with other form inputs using html, ajax and php. I'm submitting the form using ajax. Everything is working in one server, but when I moved the code to a new server, I keep getting PARTIAL FILE UPLOAD ERROR.

Sample code is given below

I am trying to run the example of a heatmap from: https://matplotlib.org/stable/gallery/images_contours_and_fields/image_annotated_heatmap.html

When I am running the code in PyCharm (Professional) in an Anaconda3 environment it results in an error message.

TypeError: set_ticks() got an unexpected keyword argument 'labels'

How do you size the axes of a marginal plot to match the size of a non-square central plot using matplotlib?

In the image, you'll see that the top marginal plot is too wide, even though it shares the x-axis labels.

Context: I'm trying to create a joint plot like in Seaborn, but with a non-square heatmap at center and bar graphs as the marginal plots. JointGrids isn't designed to work with heatmaps (which is okay, on to matplotlib!). Merging a matplotlib heatmap with subplot barplots gets me close, but I find one bargraph's axis is larger than the central heatmap even when I share axes.

Minimum working example:

My sample data start with values beginning with 700 so that there is nothing between 0 and 700. I want to cut that range out of the line plot but I also want to point the reader to that cut by visualizing it like this. This example picture is manipulated via a drawing software just to explain what I want.

Something like this is explained in the matplotlib documentation. But I do not understand what happens there in the example code. And I am not sure if it fits to my case because the example cutting data. And I just want to cut the area where is no data present.

Here is a minimal working example producing line figure where the y-axis starts at 700 not 0. Can we start from here?

When I try to run command ng lint --fix cli throws this error:

I'm trying to make a page with multiple sticky sections with horizontal scrolling (so when you're scrolling vertically as normal, you're forced to go through the horizontal gallery)

I'm referencing this codepen (https://codepen.io/johnhubler/pen/RwoPRBG) as my JS knowledge is very poor. But, as you can see in the codepen, it is only working in the first sticky section, and the second one stays still.

Hi I know this is probably a stupid question but what does this error mean in relation to my app.js file? It didn't appear until I ran my local server. Was working fine prior.
