randomizer_null_safe

Flutter package which helps in picking random color, random element from list, random numbers, random doubles and many more.

Fork of randomizer with null-safety, optimized code, new functions and example project.

Usage

• Instantiate Randomizer without seed

Use Randomizer.instance() to get same static instance everytime.

Randomizer r1 = Randomizer.instance();
Randomizer r2 = Randomizer.instance();
// r1 and r2 uses same instance

This is recommended way to use Randomizer

• Instantiate Randomizer with seed

Use Randomizer.instance(seed) to initiate Randomizer with your custom seed. This will also return a different instance of Randomizer everytime even if seed is same.

Randomizer r1 = Randomizer.instance(N1);
Randomizer r2 = Randomizer.instance(N2);
// r1 and r2 uses different instances

Only use your own seed if you know what you are doing

• Generate random color

Color color1 = randomizer.randomColor();
Color color3 = randomizer.randomColorWithOpacity();

• Get random value from a non-empty list

int num = randomizer.randomElementFromList([0, 1, 2, 3]);

• Get random integer values

int num1 = randomizer.randomInt();
int num2 = randomizer.randomInt(max: 1000);
int num3 = randomizer.randomInt(includeNegative: true);
int num4 = randomizer.randomInt(max: 1000, includeNegative: true);
int num5 = randomizer.randomIntInRange(10000, 999999);

• Get random double values

double num1 = randomizer.randomDouble();
double num2 = randomizer.randomDouble(max: 99);
double num3 = randomizer.randomDouble(includeNegative: true);
double num4 = randomizer.randomDouble(max: 99, includeNegative: true);
double num5 = randomizer.randomDoubleInRange(10, 99);
