SystemPropertyUtils class abstract
Utility class for resolving #{...}-style placeholders within strings
using system properties or environment variables.
This class provides static methods to:
- Resolve system placeholders like
#{user.name} - Configure whether unresolved placeholders should throw or be ignored
It supports default value resolution using the colon : separator, and
escaping using the backslash \.
Example (strict resolution)
final result = SystemPropertyUtils.resolvePlaceholders('Hello #{USER}');
print(result); // Throws if USER is not found
Example (lenient resolution)
final result = SystemPropertyUtils.resolvePlaceholdersWithPlaceholder(
'Hello #{USER:Guest}',
true,
);
print(result); // Hello Guest
