Annoying to have to write double literals for integer values.

[lrhn]

In Dart, unlike many other languages, integers and doubles are objects, not "primitive values". There are no special rules converting between the types on assignment (assignment generally preserves the identity of objects).

This can be annoying when you want to write something simple, like:

double x = 10;
foo(double x) => ...;
foo(42);

Here the integer number isn't allowed where a double is expected, so the program fails to compile. You have to write it as 10.0 and 42.0 to get the program compiling. This is annoying, and it feels like needless overhead when the meaning is clear.

I would be nice if you didn't have to write the extra .0, the compiler should be able to figure that out.

That's all over the place in Flutter.

Not sure why they didn't use num instead of double everywhere, but I guess it would cause inefficiencies in sensible places.

Closing, this is tracked in implementation issue #20
