PreloadConfig class

预加载全局配置

Constructors

PreloadConfig({int maxConcurrentTasks = 3, Duration defaultTimeout = const Duration(seconds: 30), int maxRetries = 2, Duration retryBaseDelay = const Duration(milliseconds: 500), bool enableLogging = true, void onError(Object error, StackTrace? stackTrace)?, Duration defaultCheckRetryDelay = const Duration(milliseconds: 300), int defaultMaxCheckRetries = 10, Future<bool> globalCheck()?, Duration? globalCheckRetryDelay, int? globalCheckMaxRetries})

const

Properties

defaultCheckRetryDelay → Duration

默认执行前检查重试间隔

final

defaultMaxCheckRetries → int

默认执行前检查最大重试次数

final

defaultTimeout → Duration

默认任务超时时间

final

enableLogging → bool

是否启用详细日志

final

globalCheck → Future<bool> Function()?

全局执行前检查 — 每个任务执行前都会调用 返回 true 表示可以执行，返回 false 则等待后重试 适用于检查应用状态（前台/后台）、网络连接、设备资源等全局前置条件

final

globalCheckMaxRetries → int?

全局检查最大重试次数（null 使用 defaultMaxCheckRetries）

final

globalCheckRetryDelay → Duration?

全局检查失败后的重试间隔（null 使用 defaultCheckRetryDelay）

final

hashCode → int

The hash code for this object.

no setter, inherited

maxConcurrentTasks → int

最大并发任务数

final

maxRetries → int

任务失败重试次数

final

onError → void Function(Object error, StackTrace? stackTrace)?

全局错误处理回调

final

retryBaseDelay → Duration

重试间隔基数（指数退避）

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited
