Hello, I added your version into my test project but exit dialog doesn't show me.

[iv4n-ga6l]

@mjablecnik The change have been made on this file https://github.com/IvanGael/widgetbook/blob/main/packages/widgetbook/lib/src/layout/mobile_layout.dart

Just a question! In the widgetbook project folder, which folder should I run in order to test the changes?

@IvanGael

In the widgetbook project folder, which folder should I run in order to test the changes?

You can run some example and test it there..

[iv4n-ga6l]

Hello @mjablecnik I tested a full example here https://github.com/widgetbook/widgetbook/tree/main/examples but I don't see any change despite the fact that some changes have been made on this file https://github.com/IvanGael/widgetbook/blob/main/packages/widgetbook/lib/src/layout/mobile_layout.dart

Hello @IvanGael 👋

Please make sure that your development environment is set up correctly. It seems like you are using the hosted Widgetbook package and not the local one, which has the changes you made.

To do so set up everything correctly, use melos as mentioned here.

[iv4n-ga6l]

@YoussefRaafatNasry I set up melos and it seems everything is good. How to use the local widgetbook package instead of which is hosted ?

[yousinix]

@IvanGael After installing melos, you need to:

1. Undo all the pubspec.lock files changes in this PR.
2. Run melos bs to install the dependancies and use the local Widgetbook version.

[mjablecnik]

@IvanGael Any progress?

[iv4n-ga6l]

@mjablecnik Not done yet. I need to take a look on this because i have tried what @YoussefRaafatNasry suggested to me but It seems there is any changes
