hello I'm trying to implement 2 recycler view in one layout, one is horizontal on the top of the layout and below that is the second which is vertical, what I want is when the vertical recycler view scrolls the horizontal will remain hide until the vertical comes back to the starting position

here is the code

I saw a video in which a person scanned a public IP(it was his SOHO network) using nmap. It showed all the open ports and other info but I don't understand how can nmap scan ports and tell which are open when there are multiple devices on that network. Is it that nmap scans all the devices on that network using that public IP and then shows a collective result or is it something else? Link for that video

I am writing a similar task manager app, i have some issues when working with BLoC:

• First, I create a Page to show all the task that have been added by pressing the FloatingActionButton() below.

• Next, when the user finished the form by hitting the FlatButton on the top right which is called SAVE, it will be submitted to Firestore, by the _submit() method in the JobForm class.

• NOTE: I also added some validator to validate the NameForm and the RatePerHourForm so it will show an error when they are null and they worked very well.

• I used a StreamBuilder() to update my JobPage() ( the first screen ), everywhen the data from Firestore changed.

• That was a summary of what I am trying to do.

BUT, when the user press the SAVE button, the Name Field and the ratePerHour Field is always empty even when i called onChanged: , in every TextField() to update them.

HERE IS MY flutter doctor:

I am working with MYSQL, and want to create a query. I have 3 tables.

What I have tried.

When the camera opens a blank camera appears for a few seconds and it always gives the same below output and stops.

Any idea how I can make the real time prediction work? without getting a false prediction as above just for one time

Below is the Camera Screen code where the prediction should happen in real time camera feed when user scans a certain surrounding

I tried to scrape links from several pages, but infortunately my loop is surely wrongly done because I obtained only 25 links awith my script.

There are 25 links by page, so here I should have 75 links, I guess it erase the previous one.
