Do you have a DMM (digital multimeter) and know how to use it?
First check that there's +5V DC on pin 1 of the USB output plug of the power adapter. If the power adapter has no voltage output it may be easier to simply replace it rather than to fix it. The specifications are shown on the adapter. Some mobile phone chargers have nearly the same specifications
Here's the [link|https://datasheets.raspberrypi.com/rpi3/raspberry-pi-3-b-plus-reduced-schematics.pdf|schematic] for the Pi3 B+ that should help you to possibly fix it.
According to the schematic there's a resettable polyfuse [link|https://www.bourns.com/pdfs/mfmsmf.pdf|MF-MSMF250/16X] connected to pin 1 of the USB port on the board.
Check that it tests 0.00 Ohms as it is designed to reset itself if it is tripped by an over voltage/current event. Then again a lightning strike is not a usual event. If it tests open circuit i.e. OL or infinity Ohms on the meter then search online using the type number to find suppliers that suit you.

Once you have +5V on the Pi board and it still doesn't work you may have to start point to point testing to find out what else has been affected.
+
Once you have cleaned up the board so that you can see if there are any components damaged (burnt or heat affected etc) check if there's +5V on the Pi board and if it still doesn't work you may have to start point to point testing to find out what else has been affected.
At least you have the schematic and what all the components and their values are, which makes it easier to find replacement parts.

Hopefully a start.
