For an app, I need a 64bit unsigned int. Looking at dart documentation I did not see how to exactly go about declaring one.
Can anyone tell me how this is done? I will use this "64bit unsigned int" in bitwise operation.

Dart does not have a native unsigned 64-bit integer.
For many operations, you can just use the signed 64-bit integer that an int
is, and interpret it as unsigned. It's the same bits. That won't work with division, though. (And if it's for the web, then an int
is a JavaScript number, and you need to do something completely different).
The simplest general approach is to use a BigInt
and use toUnsigned(64)
after you do any operations on it.
BigInt
. –
Seizure BigInt
as I need to use shifts. –
Glede >>>
operator back, you should be able to handle unsigned shifts too, but it's not there yet. –
Seizure Int16List
, but they will become int
values when read. –
Seizure Just use fixnum
You can easily create an int64
with Int64()

int
one of the bits is reserved for a sign, and only 63 bits are available to store value. I need all 64 bits to be used for value. – Glede
