Strings in Dart: Chapter Overview

Strings teaches you to work with text and time.

In this chapter, you will:

• search, cut, change, split and join text with String methods
• build long text quickly with StringBuffer, and handle emoji with runes
• create dates with DateTime, and read parts like year and weekday
• measure and add time with Duration

What each lesson covers:

• Strings: How to create strings, put values inside them, compare, search, cut, change, split and join them, build long text with StringBuffer, and handle Unicode and emoji.
• Date and Time: How to create DateTime values, read their parts, compare and subtract dates, add time with Duration, and convert dates to text and timestamps.

This chapter has 2 lessons. Plan on about 36 minutes, with 6 exercises to check what you learned. Every example is real Dart code: change it, run it again and compare the output, which is the fastest way to learn how each feature behaves.

Simple lesson: finish this chapter and you can build report cards, notices and timetables.
