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.

hashCode → int: The hash code for this object. [...]
read-only, inherited
isEmpty → bool: Returns whether the buffer is empty. This is a constant-time operation.
read-only
isNotEmpty → bool: Returns whether the buffer is not empty. This is a constant-time operation.
read-only
length → int: Returns the length of the content that has been accumulated so far. This is a constant-time operation.
read-only
runtimeType → Type: A representation of the runtime type of the object.
read-only, inherited

clear() → void: Clears the string buffer.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed. [...]
inherited
toString() → String: Returns the contents of buffer as a concatenated string.
override
write(Object? obj) → void: Adds the contents of obj, converted to a string, to the buffer.
override
writeAll(Iterable objects, [String separator = ""]) → void: Iterates over the given objects and writes them in sequence.
override
writeCharCode(int charCode) → void: Adds the string representation of charCode to the buffer.
override
writeln([Object? obj = ""]) → void: Converts obj to a String by invoking Object.toString and adds the result to this, followed by a newline.
