Equatable in Flutter is a package used to compare the object.
If we want to compare objects normally then we have to override the == operator as well as hashCode.Overriding == operator is a lengthy and very tedious process as we need to write extra code for this.If we fail to override it correctly it will not behave as we expect.
So, if you want to compare objects then Equatable is a convenient package for defining classes.Classes can be compared for equality based on their properties rather than their identity. This is especially useful when you want to compare two instances of a class based on their content rather than their memory address.
