You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: field.rs
    path of file: ./repos/flutter_rust_bridge/frb_codegen/src/library/codegen/generator/api_dart/spec_generator/class
    
    the code of the file until where you have to start completion: use crate::codegen::ir::default::IrDefaultValue;
use crate::codegen::ir::field::IrField;
use crate::codegen::ir::ty::delegate::IrTypeDelegate;
use crate::codegen::ir::ty::IrType;
use crate::utils::dart_keywords::make_string_keyword_safe;
use convert_case::{Case, Casin
    
    pub fn test_default_value_to_dart_style() {
        assert_eq!(&default_value_to_dart_style("something"), "something");
        assert_eq!(
            &default_value_to_dart_style("OneTwo.ThreeFour"),
            "OneTwo.threeFour"
        );
        assert_eq!(
            &default_value_to_dart_style("const Foo.bar()"),
            "const Foo.bar()"
        );
    }
