How does string interpolation and multiline strings work in Dart?
TL;DR: Dart uses $variable or ${expression} for string interpolation, triple quotes for multiline strings (''' or """), and r'raw strings' to disable escape sequences.
Full Answer
Dart strings support Unicode, interpolation, multiline, and raw formats. They are immutable.

Raw strings (r'...') are useful for regex patterns and file paths on Windows. Triple-quoted strings are great for JSON templates and multi-line SQL/Dart code in tests.
