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.
Properties
- 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.

Methods
-
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 tothis
, followed by a newline.override
Operators
-
operator ==(
Object other) → bool -
The equality operator. [...]
