I have a problem with displaying dynamically Text widget based on String null safety value. So, If I'm writing conditions like that:
String? _selected;
String _placeholer = "select";
Row(
children: [
if (_selected != null) Text(_placeholer) else Text(_selected!),
],
),
or
Row(
children: [
_selected!.isEmpty ? Text(_placeholer) : Text(_selected!),
],
),
Console is returning this error:
Unexpected null value.
And on the view I have red container instead of this Text. How can I fix it?
It seems like you made a mistake here.
children: [
if (_selected != null) Text(_placeholer) else Text(_selected!),
],
Change it like this:
children: [
if (_selected == null) Text(_placeholer) else Text(_selected!),
],
Much better version would be like this:
children: [
Text(_selected ?? _placeholder)
]
