+### Examples
+
+
+#### Valid code
+    
+##### ThemedComponent wrapper defines an input without a default value
+        
+```typescript
+export class TTest extends ThemedComponent<Test> {
+
+@Input()
+test;
+}
+```
+    
+##### Regular class defines an input with a default value
+        
+```typescript
+export class Test {
+
+@Input()
+test = 'test';
+}
+```
+    
+
+
+
+#### Invalid code 
+    
+##### ThemedComponent wrapper defines an input with a default value
+        
+```typescript
+export class TTest extends ThemedComponent<Test> {
+
+@Input()
+test1 = 'test';
+
+@Input()
+test2 = true;
+
+@Input()
+test2: number = 123;
+
+@Input()
+test3: number[] = [1,2,3];
+}
+```
+Will produce the following error(s):
+```
