Error: A value of type 'String' can't be assigned to a variable of type 'int'

I'm trying to implement different languages (english & spanish) in my app, this is what I was thinking:

String selectedLanguage = 'en';

const Map<String, Map<String, String>> languageLabels = {
  'en': {
    'label1': 'label in English',
  },
  'es': {
    'label1': 'label in Spanish',
  },
};

And I was planning to use it as:

static String label1 = languageLabels[selectedLanguage['label1']];

But I keep getting this error

Error: A value of type 'String' can't be assigned to a variable of type 'int'.

static String label1 = languageLabels[selectedLanguage['label1']];
___________________________________________________________^

I read that it was because of null safety, but I just don't know how to solve it.

Try assigning it this way

String? label1 = languageLabels[selectedLanguage]?['label1'];

OR

String label1 = languageLabels[selectedLanguage]?['label1'] ?? '';

OR (I do not suggest it) if you are sure you will never get null value:

String label1 = languageLabels[selectedLanguage]!['label1']!;
