It is a well known fact that keyboard shortcuts can help us a lot while developing, especially when you have a lot of code to go through and you have to find the opening and closing brackets or insert a new widget or remove one. Time is precious and I find these shortcuts help me a lot in coding in flutter. I became a fan of VS Code mainly because it’s so light weight and opens much faster than other IDEs I have worked with and have a ton of features and customizations along with extensions which can do wonders (This is just my personal opinion).
Now let’s jump into the shortcuts and see what all wonders we can do.
Firstly, I will provide you the shortcut to get all the shortcuts.
I won’t be able to explain all the default shortcuts in this article since the list is huge. You can find the list of default keyboard shortcuts and also search for shortcuts by using
CTRL+K+S as seen below:
Or you can also use
Ctrl+Shift+P to Show Command Palette with the recently used commands or also to search commands.
While coding, this is one of the important tools especially for beginners or if you get stuck somewhere and want to check for options, you can use
Ctrl+Space to get a list of curated code completion options.
For faster development in flutter you can use the quick fix tool with is
Ctrl+. , it helps in fixing the code with some additional requirements without messing with your code or your widget structure and giving you less headache of manually correcting everything. Let’s see some of the examples
As you can see below, when on any widget you can click
Ctrl+. to find the quick fix options.
Let’s explore the menu items one by one :
You can extract an existing widget and make it a local variable and magically the widget will be replaced by the variable, wherever it is used.
What if you have got a lot of code and you want to split it to different methods. It would even given you a generated name for whatever code you want to split.
But I would advice against splitting widgets to methods, instead you should create a new class as it has a lot of impact on performance, you could refer this article to know in depth why widgets should not be split into methods. You can do this easily using the next menu.
This can come a lot in handy if you want to split your widgets into smaller widgets. Hope by now you know about the importance of splitting widgets to smaller widgets and it’s impact on performance 😉.
Just click on any widget and then click
Ctrl+. and click
Extract Widget option and give a name for the new widget and click
Enter and that’s it.
Now let’s say, you wanted a
StatefulWidget, but this process only gives you a
StatelessWidget, but there is a cool way to convert the
StatefulWidget, may be by this time you would have guessed it…
Yes, you just have to click the
StatelessWidget and click
Ctrl+. and then “Ta Da” as if it’s magic you will get an option
Convert to StatefulWidget click on that and that’s it 😍
Adding padding to an existing widget is much more easier with the quick assist tool, just select
Add padding and you will get padding around your widget without messing up your widget structure.
This is used to wrap it with a
center widget, thus centers your widget.
You can use this same technique to wrap your required widget with a Column or Container or Row or StreamBuilder or any other widget or even custom widgets, to make that as your parent widget of the required widget.
But, unlike the same tool in android studio, you cannot select multiple widgets to come under a column, as of now that feature is not available.
You can also wrap with any other widget or a custom widget
There are some flutter specific shortcuts as well, which will provide some boilerplate code to work upon, which you can call by typing prefixes, in case the menu doesn’t popup you can type
Ctrl+space after typing the prefix.
stless: Create a new subclass of
stful: Create a new subclass of
StatefulWidgetand it’s associated State subclass.
stanim: Create a new subclass of
StatefulWidget, and it’s associated State subclass including a field initialized with an
Inorder to see the class hierarchy press
F4 on any
widget and in a few seconds you will be able to see the widget hierarchy.
This is very common and is used usually in any editor, you can select any word by double clicking the left mouse button over that word and you can select the whole line by clicking the left mouse button 3 times consecutively.
You can easily see behind the curtains of any widget and know it’s working or even find out the reason behind your errors or find the required parameters by going to the widget source code and reading about it, flutter provides a detailed documentation in the form of comments in the source code and can help you solve issue faster, in order to do that, it’s very easy, you just have to press
ctrl and then
left mouse click any widget to go into its source file, or you can use
F12 while cursor is on the widget.
You can cut a line by using
Ctrl+x or copy the line using
Ctrl+c when the cursor is at any point on the line and then you can use
Ctrl+v to paste the same.
You can directly go to any line number by using
Ctrl+g and typing the line number.
You can move a single line by clicking anywhere on the line and then clicking
Alt+↓ you can move the line one line up or one line down.
Or you can move a whole selection in same way.
Similarly you can use
Shift+Alt+↓ to copy a line/selection of lines up or down.
We have always come across long code where we have to select between brackets and this shortcut comes in hand during those times. First click on either of the start braces or the ending braces and then click
Shift+Alt+→ and magically all the things inside those braces will be selected, you can keep on pressing
Shift+Alt+→ to expand the selection more and you can also shrink the selection by using
you can easily find the pair of a bracket using
![While on any bracket, you can find it’s pair by using Ctrl+Shift+](https://cdn-images-1.medium.com/max/1600/1*hmFnvS5sR_IKHH5WS7xGlA.gif “While on any bracket, you can find it’s pair by using Ctrl+Shift+”)
Sometimes while we are coding and traversing through different files or implementation, we might forget how we reached to this exact code. You can easily trace your steps by using
Alt+← to see which all code you had come through to get here, you can use
Alt+→ to go forward as well.
You can easily switch between open files / tabs using
Ctrl+Tab and then if you hold down
Ctrl and keep pressing
Tab you can choose which tab you want to traverse to.
You can easily rename any widget by pressing
F2 while you are on that widget and then type the new name and then press
Thanks to Chase Adams I came to know about this wonderful keyboard shortcut, you have to take the terminal and go to the location where the workspace is and then type
code -r. and then that workspace will open in current visual code window. If you want it to open to a new window, use the command
code -n. and it will open the workspace in a new VS code window
Writing efficient code is difficult and usually it ends up being messy with the usual time constraints and hence before pushing the code to git or any other versioning tool, you would want to clean it up and make it look good with good amount of comments so that it is well maintainable and for that here are some of the keyboard shortcuts which would come in handy.
While coding, it is a best practice to follow the formatting, but sometimes we just go with the flow and at the worse case we end up with something like this:
Now you can easily format this by pressing
Alt+Shift+f to fix your indentation and reformat code.
PS:- Always put trailing commas to get this formatting to work accordingly.
You can comment any existing line by pressing
Ctrl+/ , you can use the same command to un-comment existing comments.
you can select some lines and press
Ctrl+/ to comment all lines with prefix
Alt+Shift+a to comment the selected lines by enclosing it inside the symbols
/* Your — Code */ , you can use the same command to un-comment the commented lines
Removing unused imports is a big part of cleaning up code and instead of removing them one by one, you can directly use a keyboard shortcut to do it for you. You can easily remove unused imports using
These are some of the debugging shortcuts which will come in handy, hope you don’t need any examples for the same.
F5- Start Debugging
F5- Start Without Debugging
F5- Stop Debugging
F5) - Restart Debugging (Hot Reload when debugging Flutter apps)
F5- Hot Restart (when debugging Flutter apps and in a debug session)
F9- Toggle Breakpoint
F10- Step Over
F11- Step In
F11- Step Out
I hope I have covered all the shortcuts which I could find and thought are mostly useful, follow me for more tips, tricks and flutter stuff.There are a ton more shortcuts or tips if you are using extensions and I will cover that in a different article so stay tuned 😉.
