Hi @Abhishek-P0207!
Correct me if I'm wrong, but you've just removed the "add a product" block altogether, right?
That's not what was supposed to be done:

• there are cases when we land on that page from a single product page, and in that case only we shouldn't be able to add products
• there are cases when we land on that page from a "add prices from receipt" button, and in that case we should definitely be able to add products (especially as we start with an empty list of products)

[Abhishek-P0207]

Hmm , I will fix it.

[Abhishek-P0207]

@monsieurtanuki I fixed it, but I have a doubt regarding the "Add price tags" button in the prices section.
Both "Add a receipt" and "Add price tags" go to the same page, then why separate buttons, also in the adding section we provide a radio button to switch between them.We can combine them in one single button right?

[Abhishek-P0207]

The "Add price tags" should not have option of Add an item right?
As, it is not possible to have a list of items like that of a receipt, in the form of a price tag. The receipt can contain bill for single item or multiple items right? But price tag will only contain a single item. We can add the proof of receipt, and add multiple items but i don't know how Add price tags work!!
Can you clarify this @monsieurtanuki

[monsieurtanuki]

I fixed it

You did? Where's the code?

but I have a doubt regarding the "Add price tags" button in the prices section. Both "Add a receipt" and "Add price tags" go to the same page

That's correct

then why separate buttons, also in the adding section we provide a radio button to switch between them.We can combine them in one single button right?

Don't worry, keep it that way.

[monsieurtanuki]

The "Add price tags" should not have option of Add an item right?

Yes it should

[Abhishek-P0207]

@monsieurtanuki The issue is fixed, please review it.

[monsieurtanuki]

Hi @Abhishek-P0207!
Unfortunately your solution doesn't work.
It should NOT depend on the current status (what if I switch from receipt to price tag? what if I start with an empty list and add one product?).
The solution is in the model: "hey, just don't show an 'add product' button". And that bool could be set as a final in the model creation, depending on where you opened the "add price" page.

[Abhishek-P0207]

Hmm, Interesting. I will look into it. As Lab exams are going on now, I am not able to contribute in a continuous basis. exams will be over by day after tmrw, so can i contribute from then on? I will try to fix this if I find any free time in between.
Thank you

Hi @Abhishek-P0207, and thank you for your code rewriting!
Please have a look at my comments.

Additional comments:

• I would have named the field "singleProduct" instead of "multipleProducts" (obviously with the opposite purpose), but it's just a matter of taste
• generally speaking it's not such a good idea to use default values when the default choice is not that obvious. More specifically here, without the default value the developer is explicitly asked "is that a single product model?", and it's a fair question to ask.

Suggested change

	final bool? multipleProducts,
	required this.multipleProducts,

[monsieurtanuki]

Suggested change

_multipleProducts = multipleProducts ?? false,

[monsieurtanuki]

Suggested change

	late bool _multipleProducts;
	bool showAddProductCard() {
	if (_multipleProducts == true) {
	return true;
	}
	return false;
	}
	/// "Should we support multiple products?" (instead of a single)
	final bool multipleProducts;

For the record, your previous syntax was a bit heavy:

  bool showAddProductCard() {
    if (_multipleProducts == true) {
      return true;
    }
    return false;
  }

The following would have been better:

  bool get showAddProductCard => _multipleProducts;

[monsieurtanuki]

Suggested change

	multipleProducts: multiProduct,
	multipleProducts: multipleProducts,

Please try to keep consistency between classes.

[monsieurtanuki]

Suggested change

	if (model.showAddProductCard()) const PriceAddProductCard(),
	if (model.multipleProducts) const PriceAddProductCard(),
