how do you include python .py file in flutter using chaquopy?

Question

I was try to include .py file inside my flutter project to use sklearn and numpy ,was able understand how to include .py file but could not understand how to call it in the flutter main.dart application, a small example will be helpful Thank You

Answer 1

Chaquopy lets you access Python code through a Java API. So in Flutter, you should use the same technique as you'd use to call any other Java API, which appears to be "platform channels".

There's an example here which you might find useful.

Answer 2

You don't need to call .py file, plugin calls that file internally for you. you just need to call Chaquopy.executeCode() function, with you code in it. I am stating an example for you here:

suppose you want to print a number, and below is your code :

a = 10
print(10)

what you need to do is, take the code from textinput as a string and put it in Chaquopy.execute() method:

code = 'a=10\nprint(a)'
Chaquopy.executeCode(code)

hope this helps. you don't need to call anything internally.

Answer 3

There is nothing wrong with the types constrains here. You need to declare the generics right after impl:

impl<T: Into<f64>> From<T> for Complex {
    fn from(t: T) -> Complex {
        Complex { real: t.into(), img: 0.0_f64 }
    }
}
