The property can't be unconditonally accsessed because the receiver can be null, flutter localization

What's up some guys... I am in the process of making my app available in different countries and I am doing that with flutter_localizations and intl. Everything went smooth up until the very end where I actually use the text from the different language files. Basically I'm trying to add the localization text instead of my hardcoded text, see below.

var text = AppLocalizations.of(context);
Text(text.appTitle),

In my Text widget I get the following error: "The property 'appTitle' can't be unconditionally accessed because the receiver can be 'null'". Is there a good workaround for this? Appreciate any help!

Solution

  • For Text you can do, because the text can be null while reading AppLocalizations.of(context).

    Text("${text?.appTitle}"),

    This will show null, if it doesn't find the value.

    Or checking

    if(text!=null) Text("${text!.appTitle}"),

    Use ! when you are certain it won't be null.
