Show permission disclosure page and allows required permissions and their associated services before the user can proceed.
5+
6+
This package shows a prominent in-app disclosure page for getting permissions as required by [Google Play](https://support.google.com/googleplay/android-developer/answer/9799150?visit_id=638041800350153935-369621111&p=pd-m&rd=1#prominent_disclosure&zippy=%2Cstep-provide-prominent-in-app-disclosure%2Cstep-review-best-practices-for-accessing-location%2Cstep-consider-alternatives-to-accessing-location-in-the-background%2Cstep-make-access-to-location-in-the-background-clear-to-users%2Csee-an-example-of-prominent-in-app-disclosure).
7+
Also support iOS to ensure a consistent experience.
8+
9+
In addition, permissions can be set as "required". If this is set, those required permissions will be required and if users denied it,
10+
this package will show a custom dialog and redirect user to the appropriate settings page provided by the OS.
11+
12+
## Setup
13+
1. Add the following to `pubspec.yaml`
14+
```yaml
15+
dependencies:
16+
flutter_force_permission: ^0.1.0
17+
permission_handler: ^10.2.0
18+
```
19+
2. This package depends on [permission_handler](https://pub.dev/packages/permission_handler). Perform setup according to that package.
20+
3. If any features is required, it is highly recommended to also set the `<uses-feature>` tag in AndroidManifest.xml. Refer to [relevant Android Developers page](https://developer.android.com/guide/topics/manifest/uses-feature-element) for details.
21+
22+
## Usage
23+
1. Create an instance of FlutterForcePermission, providing configuration.
24+
```dart
25+
final perm = FlutterForcePermission(
26+
FlutterForcePermissionConfig(
27+
title: 'Title',
28+
permissionItemConfigs: [
29+
PermissionItemConfig(
30+
permissions: [Permission.locationWhenInUse],
31+
required: true,
32+
itemText: PermissionItemText(
33+
header: 'Foreground Location',
34+
rationaleText: 'Rationale for Foreground location. Required.',
35+
forcedPermissionDialogConfig: ForcedPermissionDialogConfig(
36+
title: 'Please enable location permission',
37+
text: 'Please enable location permission for proper usage.',
38+
buttonText: 'Settings',
39+
),
40+
),
41+
),
42+
PermissionItemConfig(
43+
permissions: [Permission.locationAlways],
44+
itemText: PermissionItemText(
45+
header: 'Background Location',
46+
rationaleText: 'Rationale for Background location. lorem ipsum dolor sit amet.',
47+
),
48+
),
49+
],
50+
),
51+
);
52+
```
53+
2. Show the disclosure page as needed. This method will handle showing the disclosure page and requesting permissions.
54+
This function takes a [NavigatorState](https://api.flutter.dev/flutter/widgets/NavigatorState-class.html) which can be retrieved through `Navigator.of(context)` call.
55+
This is an async function. Wrap the function in an `async` block as needed.
56+
Returns a map of permission and their requested status (granted/denied/etc). Refer to [permission_handler](https://pub.dev/packages/permission_handler) for the interface.
57+
```dart
58+
final result = await perm.show(Navigator.of(context));
59+
```
60+
61+
### Styling
62+
You can set the style of the text shown by setting up a [TextTheme](https://api.flutter.dev/flutter/material/TextTheme-class.html) of the provided context.
63+
- Title uses `headline6` text style.
64+
- Item header use `subtitle1` text style.
65+
- Item body use `bodyText2` text style.
