相关疑难解决方法(0)

我想使用iOS和Android中的标准共享对话框共享图像.下面的代码主要来自https://pub.dartlang.org/packages/share,我将其用作起点(下面只有Dart和Objective-C).它目前只共享文本.

而不是Image,我不确定是最好的方法,如何将图像转换为Dart中的字节流并在iOS和Android中处理.

镖

static const _kShareChannel = const MethodChannel('example.test.com/share');
Future<Null> shareImage(Image image) {
  assert(image != null);
  return _kShareChannel.invokeMethod('shareImage', image);
}

Objective-C的

static NSString *const PLATFORM_CHANNEL = @"example.test.com/share";

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [GeneratedPluginRegistrant registerWithRegistry:self];

    FlutterViewController* controller = (FlutterViewController*)self.window.rootViewController;

    FlutterMethodChannel *shareChannel = [FlutterMethodChannel methodChannelWithName:PLATFORM_CHANNEL
                            binaryMessenger:controller];

    [shareChannel setMethodCallHandler:^(FlutterMethodCall *call, FlutterResult result) {
        if ([@"shareImage" isEqualToString:call.method]) {
            [self share:call.arguments withController:[UIApplication sharedApplication].keyWindow.rootViewController];
            result(nil);
        } else {
            result([FlutterError errorWithCode:@"UNKNOWN_METHOD"
                                       message:@"Unknown share method called"
                                       details:nil]);
        }
    }];
    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
