Building on @Hemanth Raj answer.

To convert it back you could do

List _sample = ['a', 'b', 'c'];
_sample.asMap().values.toList(); 
//returns ['a', 'b', 'c'];

Or if you needed the index for a mapping function you could do this:

_sample
.asMap()
.map((index, str) => MapEntry(index, str + index.toString()))
.values
.toList();
// returns ['a0', 'b1', 'c2']
