List list = [ ('a', (1,2)), ('b', (2,3)), ('c', (3,4)) ]

// Dart >= 2.3:
var result = { for (var v in list) v[0]: v[1] };

// Dart < 2.3
var result = Map.fromIterable(list, key: (v) => v[0], value: (v) => v[1]);

You can use Map.fromIterable:
var result = Map.fromIterable(l, key: (v) => v[0], value: (v) => v[1]);

or collection-for (starting from Dart 2.3):
var result = { for (var v in l) v[0]: v[1] };
