This is a simple package which helps you debug while writing tests. It pinpoints what is wrong with your data when comparing Equatable objects

Getting started

Add the equatable package.

Usage

const TwiceNestedEquatable tTwiceNestedEquatable = TwiceNestedEquatable(
    'id', tFlatEquatable, OnceNestedEquatable('id', FlatEquatable('id', 'title')));

const TwiceNestedEquatable tTwiceNestedEquatableWrong = TwiceNestedEquatable(
    'id', tFlatEquatable, OnceNestedEquatable('id', FlatEquatable('id', 'titleWrong')));

test(description, () {
  // assert
  equatableExpect(
            tTwiceNestedEquatableWrong, tTwiceNestedEquatable);
});

Which outputs:

Expected: 'title'
  Actual: 'titleWrong'
   Which: is different. Both strings start the same, but the actual value also has the following trailing characters: Wrong

Path: TwiceNestedEquatable -> OnceNestedEquatable -> FlatEquatable -> String (Actual) / String (Matcher)
