We use version control system to manage and gather our source codes, right. I am pretty sure most of us are using Git for version control system nowadays. Today, I will share with you some git commands that will help you to improve your git knowledge.

Remove all your local git branches except master

You may have many local branches while you are on developments. But one day, you may want to get rid of these local branches and keep only main/master branch. This command will help you.

git branch | grep -v "main" | xargs git branch -D

Undo last commit

If you want to undo your most recent commit. Follow these steps.

git commit -m "undo message"

Then reset our changes

Pretty git log format

git reset HEAD~

Normally we use to see our git log activity using git log. But we can see better with pretty formatting using this.

git log --graph --abbrev-commit --decorate --format=format:'%C(bold blue)%h%C(reset) - %C(bold green)(%ar)%C(reset) %C(white)%s%C(reset) %C(dim white)- %an%C(reset)%C(bold yellow)%d%C(reset)' --all

Deleting git branch

I wrote deleting local branches except main/master in above. In here, I will talk about deleting a specific branch both on local and remote.

Deleting on local

git branch -d <branch_name>

Deleting on remote

git push <remote> --delete <branch_name>

Cherry picking from another repository

We can apply the changes from another repository to us also.

git fetch <remote-url> <branch_name> && git cherry-pick SHA1

I’m pretty sure there are other useful tricks as well. That’s all for now.

We have to catch your domain name, hostname and url segments and use it back in your projects frequently. Today I will share a few functions to get it done easily in Laravel Framework.

getHttpHost

request()->getHttpHost(); //return domain.com

This will return the domain name like this.

request()->getHost(); // return domain.com

This also works same with above method.

getSchemeAndHttpHost

If you want to get http segments along with the domain name. You can use getSchemeAndHttpHost method.

request()->getSchemeAndHttpHost(); // return https://domain.com

url

Using the url method, you can get the current route path like this.

url()->current(); // return current existing url

You can also use request()->url() to return the url address along with http.

segment

If you need to parse your routing url , the segment will help to parse it. For example this is our current url domain.com/blog/hello

request()->segment(0); // return blog
request()->segment(1); // return hello 

The methods I wrote above are some of the useful functions if you have to deal with your URL address or hostname.

These days I studies flutter widgets a lot. From these studies, I would like to share you one thing – this is the importance of aspect ratio and how to use this widget.

Care about proportions more than exact dimensions?

When laying out your app, you often don’t care about the exact dimensions of which it will take. But you do care about the aspect ratio. You want the widget to be this wide irrespective of the actual dimensions or you want it to be slim or exactly square. Flutter solves this by providing the Aspect Ratio widget.

AspectRatio()

you give it an AspectRatio, a child, and, well , that’s it.

AspectRatio(
 aspectRatio: 3 / 2,
child:  MyWidget(),
)

Aspect ratio is the ratio between the width and height of a box. It’s often written as a fraction, like 3/2, as in three parts of width to two parts of height. But let’s not kid ourselves – it’s really just a double: 3 over 2 is just 3 divided by 2, which is 1.5 – the same thing.

AspectRatio(
 aspectRatio: 1.5,
child:  MyWidget(),
)

But don’t worry! Dart is smart enough to do the computation for you during compilation. So it’s okay and more readable to provide the aspect ratio as a fraction.

And one more thing – make sure you actually let the AspectRatio widget size it’s child. If you put AspectRatio into something like Expanded, then that will be forced by it’s parent to expand.

Expanded(
 child: AspectRatio(
  aspectRatio: 3 / 2,
  child: MyWidget(),
 ),
)

Tightly fitted widgets like Expanded don’t give their children a choice- harsh. If this happens to you, just put something like Align between the Expanded and the AspectRatio.

Expanded(
 child: Align(
 alignment: Alignment.bottomCenter,
  child: AspectRatio(
   aspectRatio: 3 / 2,
   child: MyWidget(),
  ),
 ),
)

Align will be forced by Expanded to fill the area. But it will let it’s child assume it’s own proportions.

Hope you enjoyed the article!
