How can I get a Uint8List image size?

Question

I want to find out the size of an Uint8List image before I upload it to firebase storage using

StorageUploadTask uploadTask = reference.putData(uint8ListImage);

wherein uint8ListImage is a Uint8List. Is there a way to find out the size of the Uint8List?

Solution

try this,

print(uint8ListImage.lengthInBytes);

this will print the size in bytes

Size in bytes or in pixels? If you just need the size in bytes... then you just need uint8ListImage.length

yeah, I need just size in bytes. Can you post your comment as an answer so that I can accept it as the answer?
