Here is how I did it:

1) I looked at the colours of the flags (not the symbols, only the "backgrounds")

🟥Red: 142

⬜White: 106

🟦Blue: 100

🇧🇷Green: 83

🟨Yellow: 66

👨🏿‍❤️‍👨🏿Black: 37

🍊Orange: 9

2) Number of colours (just background)

🇨🇳1 colour: 22

🇦🇹2 colours: 60

🇫🇷3 colours: 94

🇵🇸4 colours: 21

🇨🇫5 colours: 7

🇿🇦6 colours: 1

So the majority has 3 colours.

Those colours will be Red, White and Blue.

3) Organisation of the flag

🇵🇸 Horizontal: 95

🇻🇦 Vertical: 31

🇨🇳 Uniform: 25

🇵🇸 Left triangle: 17

🇵🇼 Round: 14

🇨🇬 Diagonal: 13

🇯🇲 Cross: 12

🇱🇷 Many strips of two colours: 9

🇬🇩 Other:17

Horizontal highly wins.

Note: 1 flag can be in various categories, that explains why uniform flags are more numerous than 1 coloured flags.

4) Order of the stripes.

I looked at the order of apparition of red, blue and white colours on tricoloured flags (verticals and horizontals).

🟥Red:

22 times 1st place

5 times 2nd

31 times 3rd

Most of the time, when red appears in a tricoloured flag, it is in 3rd position.

🟦Blue:

17 times 1st

7 times 2nd

12 times 3rd

Blue tends to be 1st

⬜White:

6 times 1st

34 times 2nd

2 times 3rd

White tends to be 2nd

Perfect!

So the order is blue, white, red.

Now let's look at the symbols.

5) Occurrences of symbols:

⭐Stars: 67

🚫None: 65

🧥Coats of arms: 31

🌙Moons: 15

🐬 Animal: 11

🇬🇧 An other flag: 10

🔪others: 17

Surprise! More "stars" than "none"! The flag will be stellar

So let's dive into the stars:

6) Position of the Stars:

Left: 31 (Including the majority (18) on top left)

Center: 22

Other: 13

The star will be top left

7) Number and shapes

The relative but clear majority of the stellar flags has 1 star.

The clear majority of stars has 5 branches.

8) Colours of the star.

27 flags have white stars 🐻‍❄️

14 yellow ✨

11 red ♥️

7 other 🇸🇹

The star will be white

So, the final flag has three stripes, horizontal, with blue at the top, white at the centre and red at the bottom, and a white star at the top left.
