Before running:

1. put all .png in the data\flutter_assets\assets\cards folder (at least one card; no whitespace characters in the names);
2. put the four .mp3 files in the data\flutter_assets\assets folder (default.mp3, positive.mp3, negative.mp3, funny.mp3);
3. write the RGB color for the background in the data\flutter_assets\assets\colorRGB.txt file;
4. start the program.

IMPORTANT: the program will not run if there isn't at least one card and all the needed files.

Setup:

• long press on a card to add/remove (enable/disable) it from the pool;
• single press on a card to increase its rarity (1 to 6 and back);
• set the number of times a card can be drawn, set as -1 if unlimited;
• set the marker of each card as A, B or All (by clicking the button);
• set the sound to be played when drawn (by clicking the button);

Draw steps:

1. randomly select a rarity;
2. randomly select a card of such rarity;
3. play the related .mp3 sound;
4. 1.5s animation "from the right" that makes the drawn card appear;
5. the card stays for 45 seconds;
6. hide the card;
7. add the drawn card to the log file;
8. reduce by one the number of uses left and disable the card if it reaches 0.

If there isn't any available card of the randomly selected rarity, it first checks the lower rarities and then the higher rarities.

e.g.: if Rarity 4 is selected and it has no cards, the check order is 3-2-1-5-6. If there isn't any card available, it returns the first card whether is active/drawable or not.

If no card is found (so there isn't any card avaliable), it returns the card at index 0.

The pool can be made by A cards, B cards or All.

Functions:

• DRAW: draws a card, shows it and, after 45 seconds, hides it
• ALL/A/B: set the marker from which draw the random card
• LAST: pop the last card from the stack (it remains until CLEAR)
• CLEAR: hide the current big card
• INDEX: set the index of a specific card
• SHOW: show the card of the specified index that ovverides the last card (it remains until CLEAR)
