encodeDstBufMaxLen function
Determine maximum encoded byte length for source containing srcLen
bytes.
If withZero
is true, the length is increased by 1 to allow room for a 0x00
byte to be appended to the end
Implementation
int encodeDstBufMaxLen(int srcLen, {bool withZero = false}) {
return srcLen + (srcLen + 253) ~/ 254 + (withZero ? 1 : 0);
}
