I am trying to build a form for a friend. I've tried doing tableviews, but doing so all the sub pages will have different info to fill in. So I wasn't sure if the best way to do this Is by building each page inside form different and not as a tableview. However way I go about this the print button only shows up once all pages have been filled
Questions I have:
Is it difficult to print all three pages info from AirPrint?
What is the best way to build this? Is it still tableviews?
If not using route of tableviews how do I add up the empty text boxes to bring back a percentage bar?
My first page I have set up is a tableview, if that is the way to do that how can I make a separate view for each row?
If you are looking to build a form I would suggest using the library found here: https://github.com/xmartlabs/Eureka. The library includes a lot of different types of fields and validations for different data types.
In order to create an action from selecting a button you can use the onCellSelection callback like this:
+++ Section()
<<< ButtonRow() {
$0.title = "Tap to force form validation"
}
.onCellSelection { cell, row in
//Do something here once the row has been tapped
}

A friend of mind started a flutter project. He asked me if it is possible to set a button like the floating button of whatsapp and which will be movable by the user.
Here you need to code a container as a button and add a custom animation if that is the question you're asking.
If not What you are looking for is a Draggable widget. You can then handle the translation using onDraggableCanceled which is passed and offset that you can be used to update the placement - https://flutter.dev/docs/cookbook/effects/drag-a-widget
And there is a couple of animation we can do for a button in a flutter.
Refer to this - https://medium.com/flutter-community/animated-send-button-in-flutter-94c1834268b1
There are many ways to do this, for the sake of simplicity I would prefer you to check out Stack Widget, where you can give coordinates to each Widget(button in your case) and move them.

i have a gridView List and when i click on one I want it to enlarge to display more information almost like a dialog box over current content.
Something like this in the picture. Thank you in advance.
I can't paste the full code, but you might use a Stack as the simplest approach.
The easiest way, without animation, is having the GridView as the first child, and when clicking the Tile, pass the tile info, call setState()... and redraw the stack with whatever overlay u want with the selected content view.
When you get that in place, you might include Animated widgets to work on the transition.
Another options is to use Overlays, go to the bottom of this Medium article, to understand how it works, it is applied to a menu, but the same concept will work for you. Maybe this is a neater approach.
Another cool option might be the use of Hero animations, but I dont know if you can manage to use within the same BuildContext, depends on how you will build the view.
Best of luck!

I understand how to change the text of a label by pressing one button. But what I want is to only be able to change the text after pressing two buttons. I have a table with names(all buttons) on the left column and specific stats on the top row(all buttons as well) to keep stats. I want to be able to press the name of a person and certain stats to change that corresponding label.
[I know, the code below is very basic, but I think keeping it as simple as possible helps beginners understanding the basic concepts.]
Create trackers for both buttons that keep track of whether the button has been pressed:
var pressedB1: Bool = false
var pressedB2: Bool = false
Check for the trackers' states in the buttons' actions:
#objc func pressedButton1(button: UIButton) {
pressedB1 = true
if pressedB2 {
//change label's text
}
}
...and the same for the other button.
Improving this code, you could use the buttons' tags, a single function for the buttons' actions, etc.. You could also use the buttons' control states which would also work better UX-wise.

I have a custom UITableViewCell and cell have 5 label like
Name : ram
DOB : 10/12/2012
Email:ram#gmail.com
Phone :1234567890
Address : Bangalore
In the ViewController I'm showing one popup so that user can select what field he want to see in the table view. So how to achieve this while user can also select these fields randomly than there will be space in between two fields , how to handle all these any suggestion ?
You have a maximum of 5 possible items to display.
Say the user taps on the button to display the popup, and choose to display 3 of the 5 items.
You could then simply create 3 labels, add them to the cells contentView, and change the height for that cell depending on the total height of the displayed labels.
