Adding Duplicate items to the Dropdown widget fails to provide helpful error message. #43333
Description
Steps to Reproduce
- Set final XXXController = TextEditingController(text: "XXX");
- In the items,
<String>['XXX', 'YYY', 'ZZZ', 'XXX'] // XXX is repeated.
.map<DropdownMenuItem<String>>((String value) {
return DropdownMenuItem<String>(
value: value,
child: Text(value),
);
- Run and the test error is not very descriptive at describing, that the issue is a result of non-unique items.
Target Platform:
- Only tested on IOS Emulator
Target OS version/browser: - Built on Darwin (Mac MacOS Mojave)
