StringBuffer class Null safety

A class for concatenating strings efficiently.

Allows for the incremental building of a string using write*() methods. The strings are concatenated to a single string only when toString is called.

Implemented types

Constructors

StringBuffer([Object content = ""])
Creates the string buffer with an initial content.

read-only
length → int
