append method
Treat the contents of this String as the name of a file
and append line
to the file.
newline
specifies the line termination character.
If you don't want a newline appended then pass an empty
string to newline
.
newline
defaults to '\n'.
e.g.
'.bashrc'.append('export FRED=ONE');
Implementation
void append(String line, {String newline = '\n'}) {
FileSync(this)
..append(line, newline: newline)
..close();
}
