+Custom fields are also type-safe in templates. The `FlashMessage` component exposes the properly typed flash object with your custom fields:
+
+```gjs
+import { FlashMessage } from 'ember-cli-flash';
+
+<template>
+  {{#each this.flashMessages.queue as |flash|}}
+    <FlashMessage @flash={{flash}} as |component flash close|>
+      {{flash.message}}
+      {{flash.category}}  {{! ✓ Typed as 'system' | 'user' | 'background' | undefined }}
+      {{#if flash.action}}
+        <button type="button" {{on "click" flash.action}}>Action</button>
+      {{/if}}
+    </FlashMessage>
+  {{/each}}
+</template>
+```
+
+### Typing Dynamically Registered Methods
+
+When you configure custom `types` in `flashMessageDefaults`, the service dynamically creates convenience methods for each type at runtime. The base class already declares types for the default methods (`success`, `info`, `warning`, `danger`, `alert`, `secondary`), but TypeScript doesn't automatically recognize any custom types you add.
+
+To get type safety for custom type methods, declare them explicitly in your service subclass:
+
+```typescript
+import { FlashMessagesService } from 'ember-cli-flash';
+import type { FlashObjectOptions } from 'ember-cli-flash';
+
+interface CustomFlashFields {
+  id?: string;
+  category?: string;
+}
+
+type Options = FlashObjectOptions & CustomFlashFields;
+
+export default class MyFlashMessages extends FlashMessagesService<CustomFlashFields> {
+  // Only declare custom types not in the base class
+  // (success, info, warning, danger, alert, secondary are already typed)
+  declare error: (message: string, options?: Options) => this;
+  declare custom: (message: string, options?: Options) => this;
+
+  get flashMessageDefaults() {
+    return {
+      ...super.flashMessageDefaults,
+      types: ['error', 'success', 'warning', 'custom'],
+    };
+  }
+}
+```
+
+This pattern uses TypeScript's `declare` keyword to inform the type system about methods that exist at runtime but aren't defined in the base class types.

 guiding principle here is that changelogs are for humans, not machines.
 
 When reviewing merged PR's the labels to be used are:
 
-* breaking - Used when the PR is considered a breaking change.
-* enhancement - Used when the PR adds a new feature or enhancement.
-* bug - Used when the PR fixes a bug included in a previous release.
