 str.toStringAsFixed(0);

simply add this to your string it removes the string after the dot(.).

With regular expression:

https://stackoverflow.com/a/624877/8619512

Try this:

(.+?)(.[^.]*$|$) This will:

Capture filenames that start with a dot (e.g. ".logs" is a file named ".logs", not a file extension), which is common in Unix. Gets everything but the last dot: "foo.bar.jpeg" gets you "foo.bar". Handles files with no dot: "secret-letter" gets you "secret-letter".

Try with : 

print(abc.replaceAll('.', ''));

or 

with Regx: 

print(abc.replaceAll(RegExp('[^a-z0-9_]+'),''));

Use

filename = abc.split(".")[0]

It's that simple :)
