FloatConverter class Null safety

Converts arbitrary values into float using extended conversion rules:

  • Strings are converted to float values
  • DateTime: total number of milliseconds since unix epoсh
  • Boolean: 1 for true and 0 for false

Example

var value1 = FloatConverter.toNullableFloat('ABC'); // Result: null
var value2 = FloatConverter.toNullableFloat('123.456'); // Result: 123.456
var value3 = FloatConverter.toNullableFloat(true); // Result: 1
var value4 = FloatConverter.toNullableFloat( Date()); // Result: current milliseconds
