Passing custom object through method channel flutter
You can pass data in hash map.
In Android:
result.success(hashMapOf( "CREDITS" to user.credits, "EMAIL" to user.email, ...))In iOS:
let data: [String: Any] = [...]result(data)In Flutter:
final result = await platform.invokeMethod<Map<String, dynamic>>('loginUser', ...);final credits = result['CREDITS'] as String;final email = result['EMAIL'] as String;...
you can use invokeMapMethod which is an implementation of invokeMethod that can return typed maps.like this :
final result = await platform.invokeMapMethod('loginUser', ...);or you can pass json object as string like that :
in android
platform.success( "{\"CREDITS\":\"${user.credits}\",\"EMAIL\":\"${user.email}\",\"LAST_ACTIVE\":\"${user.lastActiveAt}\"}")in flutter
var result = await methodChannel.invokeMethod('loginUser' , '');var json = json.decode(result);var credit = json['CREDITS'];var email = json['EMAIL'];var lastActive = json['LAST_ACTIVE'];
