StringView class Null safety

A wrapper class for Strings which adds a cursor tracking an offset in the string.

A StringView allows a String to be consumed from start to end, as well as providing operations that are especially useful for argument parsing.

Constructors

StringView(String buffer, {bool isRestBlock = false}): Create a new StringView wrapping buffer.

buffer → String: The string wrapped by this StringView.
final
current → String: The character at the current cursor position.
read-only
end → int: The largest possible index for the cursor.
read-only
eof → bool: Whether the entire buffer has been consumed.
read-only
hashCode → int: The hash code for this object.
read-onlyinherited
history ↔ List<int>: A record of all the previous indices the cursor was at preceding an operation.
read / write
index ↔ int: The current index of the cursor in buffer.
read / write
isRestBlock ↔ bool: Whether remaining should be considered to be one "block" of text, which getQuotedWord will return all of.
read / write
isWhitespace → bool: Whether the current character is whitespace.
read-only
remaining → String: The part of buffer that has yet to be consumed, spanning from index to the end of buffer.
read-only
runtimeType → Type: A representation of the runtime type of the object.
read-onlyinherited

copy() → StringView: Create a copy of this StringView, with an identical buffer and index.
escape(int start, int end) → String: Escape and return a portion of buffer.
getQuotedWord() → String: Consume and return the next word or quoted portion in buffer.
getWord() → String: Consume and return the next word in buffer, disregarding quotes.
isEscaped(int index) → bool: Return whether the character at index is escaped.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed.
inherited
skipString(String s) → bool: Skip over s and return true if s matches the text after the cursor, and return false otherwise.
skipWhitespace() → void: Skip to the next non-whitespace character in buffer.
toString() → String: A string representation of this object.
override
undo() → void: Revert the previous operation if there is one.
