print(folderPath);
String thumb = await Thumbnails.getThumbnail(
thumbnailFolder: folderPath,
videoFile: videoPathUrl,

return thumb = model.thumbnail;
}
}

Answer 1

I Have Found a Solution "the Problem is not with the plugin or the method it adopts to store the Image" The problem is that it is not clear that how should a Unit8List is to be stored in the database.
In My case. __
I am Using this code to Store the Image.
_getThumb(videoPathUrl) async {
final thumb = await VideoThumbnail.thumbnailData(
video: videoPathUrl,
imageFormat: ImageFormat.JPEG,
maxWidth: 100,
maxHeight: 100,
quality: 75,
);
}
Then I am Using this final thumb to be saved against my VideoModel Variable of thumbnail
_getThumb(videoPathUrl) async {
final thumb = await VideoThumbnail.thumbnailData(
video: videoPathUrl,
imageFormat: ImageFormat.JPEG,
maxWidth: 100,
maxHeight: 100,
quality: 75,
);
print('thumbnail $thumb'); //Add these lines
model.thumbnail = thumb; //Add these Lines
return thumb; //Add these lines
}
And Once i have saved it i can see the print result in my debug console. Once i have that i am sure that it is saved.
Now i have to save it as a Blob in my db not as a String.
and thumbnail should be a Unit8List variable not a String Variable.
See the example
and in database
I am Also adding the full Video Model and DbHelper files for Others to use.
VideoModel.dart
import 'dart:typed_data';
import 'model.dart';
class VideoModel extends Model {
static String table = 'videos';
int id;
String videoName;
String video;
Uint8List thumbnail;
VideoModel({
this.id,
this.videoName,
this.video,
this.thumbnail,
});
static VideoModel fromMap(Map<String, dynamic> map) {
return VideoModel(
id: map["id"],
videoName: map['videoName'].toString(),
video: map['video'],
thumbnail: map['thumbnail'],
);
}
Map<String, dynamic> toMap() {
Map<String, dynamic> map = {
'id': id,
'videoName': videoName,
'video': video,
'thumbnail': thumbnail,
};
if (id != null) {
map['id'] = id;
}
return map;
}
}
DbHelper.dart
abstract class DB {
static Database _db;
static int get _version => 1;
static Future<void> init() async {
if (_db != null) {
return;
}
try {
var databasesPath = await getDatabasesPath();
String _path = p.join(databasesPath, 'video.db');
_db = await openDatabase(_path, version: _version, onCreate: onCreate);
} catch (ex) {
print(ex);
}
}
static void onCreate(Database db, int version) async {
await db.execute(
'CREATE TABLE videos (id INTEGER PRIMARY KEY AUTOINCREMENT, videoName STRING, video STRING, thumbnail BLOB)');
}
static Future<List<Map<String, dynamic>>> query(String table) async =>
_db.query(table);
static Future<int> insert(String table, Model model) async =>
await _db.insert(table, model.toMap());
static Future<int> update(String table, Model model) async => await _db
.update(table, model.toMap(), where: 'id = ?', whereArgs: [model.id]);
static Future<int> delete(String table, Model model) async =>
await _db.delete(table, where: 'id = ?', whereArgs: [model.id]);
static Future<Batch> batch() async => _db.batch();
}
Now when you have done these edits You can just all your image using
Image.memory(add your Image Here);
see example:
I hope that this will help some of you if you need help Let me know. Thanks
