Dark mode can be achieved using Qt5.
Download the unit: https://github.com/doublecmd/doublecmd/blob/master/src/platform/win/udarkstyle.pas
and call it in your application:
Code: Pascal  [Select][+][-]
  1. udarkstyle.ApplyDarkStyle;

You must set the widgetset for your project to qt5

In Lazarus ? Trivial, no tutorial needed.
In the project you are working on, Project->ProjectOption->AdditionsAndOverRides(down near bottom)->LCLWidgetType. Add qt5

If your project has several modes, do that for each.

But you will also have to install Qt5 libraries on your Windows box, thats possibly more of a task and one I cannot help with. Your  end user will also need the qt5 libraries by the way.

Total guess work, I have never used QT on Windows.

But I can get any colour scheme I like with Qt5 and Linux, with no extra code in the app itself. 

(Obviously, Zeljk knows this but for OP)  An external app, supplied by the QT people themselves (called qt5ct on Linux) sets up colour profiles, you launch your app with an Env Var that tell it, a QT app, which colour profile to use.
Works flawlessly on Linux, never tried it anywhere else.

Dark theme, dark theme...
Did anyone note that at paweld's picture PageControl is drawn inconsistently with other controls? And black font on dark grey background is almost unreadable?

Hello.

You may also consider the MSEgui widgetset.
It dont need to install any dependencies, works for Windows, Linux, FreeBSD, is 100% Pascal code and you may use dark, light, what-ever-theme you want.

Hi! Nice to know.
Can you help me to understand the step number 7?

"In 'Project'-'Open' select 'sourcedirectory/apps/demo/demo.prj'."

https://github.com/mse-org/mseide-msegui/#installation

I can't find it.  %)

Hello.

When you have downloaded and unzipped the source (from
https://github.com/mse-org/mseide-msegui/archive/master.zip)

in the directory of your choice (let say "sourcedirectory"), open the project  '/sourcedirectory/apps/demo/demo.prj'.

In my case it is: /home/fred/mseide-msegui/apps/demo/demo.prj

B-b-but open with what? How?

Lazarus can't open that file (unless text) and MSEide even.

I tried to go to:
Project > Options > Tab "Storage", hit the "..." button, and saved it.

Then i Opened it:
Project > Open > 'demo.prj' and run (Continue).

But I'm getting the following error:

"gdb.exe -interpreter=mi -nx"

Lazarus can't open that file (unless text) and MSEide even.

With MSEide project files (.prj) are loaded with the menu item "Project" "Open".

Lazarus (afaik) cannot load 'prj' files.

Do you have gdb.exe installed on your system?

[EDIT] If gdb.exe is located in a custom path you may adjust it in menu "Settings" "Configure MSEide" "Debugger path".
