The versatile text field for every design
Validate a text field and produce a user-friendly message.
Highlights:
- Validate a text field based on character size
- Validate a text field based on word size
- Validate a URL text field
- Produce meaningful messages that can be understood by the user
- Can produce multiple messages for success or failure
A few examples:
Create a message:
final tooSmallMessage = CopperframeMessage(label: 'Too small',level: CopperframeMessageLevel.error, category: 'length');Create a rule:
final minRule = CopperframeFieldRule(name: 'chars more than',options: {'text#minChars': '1'}, successMessages: [], failureMessages: [tooSmallMessage]);Create a field event:
final event = CopperframeFieldEvent(name: 'OnCharChange', rules: [minRule]);Create a text field event builder:
final builder = TextFieldEventBuilder(fieldEvent: event, metricStoreHolder: metricStoreHolder, optionsInventory: optionsInventory, widgetOptions: {'pageRow': 'row123'}, pageOptions: {'page': 'page789'});Build a text field event using the builder:
final textRule = builder.build();Validate the text field:
textRule.validate('some text');
