Currently, there are 21 `.resolveWith()` calls in example files.
This pull request changes 11 of them to use the new `.fromMap()` constructor. (Seven of them are now `const`!)
```dart
ListTile(
iconColor: WidgetStateColor.fromMap(<WidgetStatesConstraint, Color>{
WidgetState.disabled: Colors.red,
WidgetState.selected: Colors.green,
WidgetState.any: Colors.black,
}),
// The same can be achieved using the .resolveWith() constructor.
// The text color will be identical to the icon color above.
textColor: WidgetStateColor.resolveWith((Set<WidgetState> states) {
if (states.contains(WidgetState.disabled)) {
return Colors.red;
}
if (states.contains(WidgetState.selected)) {
return Colors.green;
}
return Colors.black;
}),
),
```

@nate-thegrate The new syntax is shorter and the main benefit turned out to be the equality problem it solved. Nonetheless, while working with it those days, I found it difficult to work with it when debugging is involved.
With the new syntax, I did not find a convenient way (other than adding breakpoint into WidgetStateMapper.resolve which is not very friendly when debugging issues with dozen of resolved colors or other properties). Any idea to mitigate this is welcomed. |

Fair point! I agree that there's a tradeoff between using a callback vs. a map in terms of verbosity/performance/debugging. I bet there are a lot of different ways we could go about improving the debugging experience. Currently there's a way to conveniently convert from stateless → stateful widget; perhaps the same could be done for map → callback.
I'll keep this in mind and will try to come up with some alternatives too. |
