MapPropertySource class

A PropertySource implementation backed by a Map of key-value pairs.

This class allows accessing properties from an in-memory map, making it suitable for programmatically defined configurations such as application defaults, test configurations, or runtime-supplied settings.

It supports property lookup via containsProperty and getProperty.

Example usage:

final config = {
  'app.name': 'JetLeaf',
  'app.port': 8080,
};

final propertySource = MapPropertySource('defaultConfig', config);

print(propertySource.containsProperty('app.name')); // true
print(propertySource.getProperty('app.port')); // 8080

This can be added to a MutablePropertySources collection for use with a PropertySourcesPropertyResolver.
