integer_literal_out_of_range

The integer literal {0} can't be represented in 64 bits.

The analyzer produces this diagnostic when an integer literal has a value that is too large (positive) or too small (negative) to be represented in a 64-bit word.

The following code produces this diagnostic because the value can't be represented in 64 bits:

var x = 9223372036854775810;

If you need to represent the current value, then wrap it in an instance of the class BigInt:

var x = BigInt.parse('9223372036854775810');
