Properties

context → BuildContext
Build context
final
hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
pattern → Pattern
The final Pattern pattern; line is declaring a final variable pattern of type Pattern. This variable is used to store a regular expression pattern that matches the different text patterns that the NixyTextFieldController class supports, such as URLs, checkboxes, and code blocks. The regular expression pattern is created by joining the keys of the patterns map with the | character, which means "or" in regular expressions. The multiLine: true parameter is used to indicate that the regular expression should match across multiple lines. This pattern variable is used in the splitMapJoin method in the buildTextSpan method to split the text into different parts based on the regular expression pattern.
final
patterns → Map<String, TextStyle>
final Map<String, TextStyle> patterns; is declaring a final variable patterns of type Map<String, TextStyle>. This variable is used to store the different text patterns and their corresponding text styles that the NixyTextFieldController class supports, such as URLs, checkboxes, and code blocks. The keys of the map are the pattern strings, and the values are the corresponding TextStyle objects that define how the text should be styled when that pattern is matched.

override
clear() → void

inherited
removeListener(VoidCallback listener) → void
