Flutter \n\n not breaking lines unless hard-coded string

I can see that Flutter allows me to use "\n\n" in a string and it causes a line break to appear in a Text item:

final String answer = "This is my text.\n\n"
    "Here is the 2nd line.";

This is my text.

Here is the 2nd line.

However, when I try to use content pulled from firebase, and set in a variable, the line break ("\n") is actually printed:

final String answer = faq['answer'];

Shows:

This is my text.\n\nHere is the 2nd line.

How can I get my "\n\n" to actually show up as line breaks?

Solution

  • Firestore doesn't support any escape sequences within string values. If you write "\n" in a string, you're going to get exactly that back when you read it.

    So you can try something like this:

    final String answer = (faq['answer'] as String).replaceAll("\\n", "\n");
