14  String

14.1 String Interpolation

14.1.1 Multi-line String Literals

Triple quotes (most similar to Python):

String multiLine = '''
This is a multi-line string
just like Python's triple quotes.
You can include line breaks naturally.
''';

// Or with double quotes
String anotherMultiLine = """
This also works with double quotes.
Line breaks are preserved.
""";

Adjacent string concatenation:

String concatenated = 'This is line one '
    'and this continues on the same logical line '
    'but split across multiple physical lines.';

14.1.2 String Interpolation in Multi-line Strings

Dart’s string interpolation works great with multi-line strings:

String name = 'Dr. Smith';
int age = 35;

String profile = '''
Doctor Profile:
Name: $name
Age: $age
Specialty: ${name.contains('Dr') ? 'Medical' : 'Unknown'}
''';

14.1.3 Raw Multi-line Strings

Use r prefix to create raw strings (no escape sequences processed):

String rawMultiLine = r'''
This is a raw multi-line string.
\n won't create a new line
${name} won't interpolate
''';

The triple quote syntax (''' or """) is the most direct equivalent to Python’s approach and is commonly used in Flutter for things like:

• Multi-line text widgets
• SQL queries
• JSON templates
• Documentation strings

This should feel quite familiar coming from your Python background!
