• Removed deprecated
• Fix instances of variables declarations (trivial)
• Fix all 'ng lint' errors and warnings
• Updated .vscode settings and recommended extensions (handy for debugging purpose)

Enjoy!

Hi Fabio, I was looking forward for this update. I'm curious what changes in flex-layout 7, I've an app based on this template and after I updated to angular 7 , by my own, the only thing broken was the flex-layout. I noticed the you changed from fxFlex to fxFlex="" in some places but it was not enough for me. Do you have details regarding update flex-layout to 7?

I hope this PR is accepted asap

Hi.
I don't have much info...
I think this small config for your module can do the job...

FlexLayoutModule.withConfig({addFlexToParent: false})

but take a look at BREAKING CHANGES for version 6.0.0-beta16
https://github.com/angular/flex-layout/blob/master/CHANGELOG.md
where the four configurations tokens:

• ADD_FLEX_STYLES
• ADD_ORIENTATION_BREAKPOINTS
• DISABLE_DEFAULT_BREAKPOINTS
• DISABLE_VENDOR_PREFIXES
  have been replaced with:
• LAYOUT_CONFIG

Also this issue
give you an idea about how fix it.
