+ 
+ ### Usage
+ The three main classes in FMDB are:
+
+ - `FMDatabase` - Represents a single SQLite database.  Used for executing SQL statements.
+ - `<FMResultSet>` - Represents the results of executing a query on an `FMDatabase`.
+ - `<FMDatabaseQueue>` - If you want to perform queries and updates on multiple threads, you'll want to use this class.
+
+ ### See also
+ 
+ - `<FMDatabasePool>` - A pool of `FMDatabase` objects.
+ - `<FMStatement>` - A wrapper for `sqlite_stmt`.
+ 
+ ### External links
+ 
+ - [FMDB on GitHub](https://github.com/ccgus/fmdb) including introductory documentation
+ - [SQLite web site](http://sqlite.org/)
+ - [FMDB mailing list](http://groups.google.com/group/fmdb)
+ - [SQLite FAQ](http://www.sqlite.org/faq.html)
+ 
+ @warning Do not instantiate a single `FMDatabase` object and use it across multiple threads. Instead, use `<FMDatabaseQueue>`.

+/** Execute single update statement
+
+ This method executes a single SQL update statement (i.e. any SQL that does not return results, such as `UPDATE`, `INSERT`, or `DELETE`. This method employs [`sqlite3_prepare_v2`](http://sqlite.org/c3ref/prepare.html) and [`sqlite_step`](http://sqlite.org/c3ref/step.html) to perform the update. Unlike the other `executeUpdate` methods, this uses printf-style formatters (e.g. `%s`, `%d`, etc.) to build the SQL. Do not use `?` placeholders in the SQL if you use this method.
+
+ @param format The SQL to be performed, with `printf`-style escape sequences.
+
+ @param ... Optional parameters to bind to use in conjunction with the `printf`-style escape sequences in the SQL statement.
+
+ @return `YES` upon success; `NO` upon failure. If failed, you can call `<lastError>`, `<lastErrorCode>`, or `<lastErrorMessage>` for diagnostic information regarding the failure.
+
+ @see executeUpdate:
+ @see lastError
+ @see lastErrorCode
+ @see lastErrorMessage
+ 
+ @note This method does not technically perform a traditional printf-style replacement. What this method actually does is replace the printf-style percent sequences with a SQLite `?` placeholder, and then bind values to that placeholder. Thus the following command
+
+    [db executeUpdateWithFormat:@"INSERT INTO test (name) VALUES (%@)", @"Gus"];
+
+ is actually replacing the `%@` with `?` placeholder, and then performing something equivalent to `<executeUpdate:>`
+
+    [db executeUpdate:@"INSERT INTO test (name) VALUES (?)", @"Gus"];
+
+ There are two reasons why this distinction is important. First, the printf-style escape sequences can only be used where it is permissible to use a SQLite `?` placeholder. You can use it only for values in SQL statements, but not for table names or column names or any other non-value context. This method also cannot be used in conjunction with `pragma` statements and the like. Second, note the lack of quotation marks in the SQL. The `VALUES` clause was _not_ `VALUES ('%@')` (like you might have to do if you built a SQL statement using `NSString` method `stringWithFormat`), but rather simply `VALUES (%@)`.

+NS_ASSUME_NONNULL_BEGIN
+
+/** To perform queries and updates on multiple threads, you'll want to use `FMDatabaseQueue`.
+
+ Using a single instance of `<FMDatabase>` from multiple threads at once is a bad idea.  It has always been OK to make a `<FMDatabase>` object *per thread*.  Just don't share a single instance across threads, and definitely not across multiple threads at the same time.
+
+ Instead, use `FMDatabaseQueue`. Here's how to use it:
+
+ First, make your queue.
+
+    FMDatabaseQueue *queue = [FMDatabaseQueue databaseQueueWithPath:aPath];
+
+ Then use it like so:
+
+    [queue inDatabase:^(FMDatabase *db) {
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:1]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:2]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:3]];
+
+        FMResultSet *rs = [db executeQuery:@"select * from foo"];
+        while ([rs next]) {
+            //…
+        }
+    }];
+
+ An easy way to wrap things up in a transaction can be done like this:
+
+    [queue inTransaction:^(FMDatabase *db, BOOL *rollback) {
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:1]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:2]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:3]];
+
+        if (whoopsSomethingWrongHappened) {
+            *rollback = YES;
+            return;
+        }
+        // etc…
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:4]];
+    }];
+
+ `FMDatabaseQueue` will run the blocks on a serialized queue (hence the name of the class).  So if you call `FMDatabaseQueue`'s methods from multiple threads at the same time, they will be executed in the order they are received.  This way queries and updates won't step on each other's toes, and every one is happy.
+
+ ### See also
+
+ - `<FMDatabase>`
+
+ @warning Do not instantiate a single `<FMDatabase>` object and use it across multiple threads. Use `FMDatabaseQueue` instead.
+ 
+ @warning The calls to `FMDatabaseQueue`'s methods are blocking.  So even though you are passing along blocks, they will **not** be run on another thread.

+ BREAKING CHANGES:
+
+ December 17, 2018:
+  - Changed designated initializer on FlutterEngine
+
+ October 5, 2018:
+  - Removed FlutterNavigationController.h/.mm
+  - Changed return signature of `FlutterDartHeadlessCodeRunner.run*` from void
+ to bool
+  - Removed HeadlessPlatformViewIOS
+  - Marked FlutterDartHeadlessCodeRunner deprecated
+
+ August 31, 2018: Marked -[FlutterDartProject
+ initFromDefaultSourceForConfiguration] and FlutterStandardBigInteger as
+ unavailable.
+
+ July 26, 2018: Marked -[FlutterDartProject
+ initFromDefaultSourceForConfiguration] deprecated.
+
+ February 28, 2018: Removed "initWithFLXArchive" and
+ "initWithFLXArchiveWithScriptSnapshot".
+
+ January 15, 2018: Marked "initWithFLXArchive" and
+ "initWithFLXArchiveWithScriptSnapshot" as unavailable following the
+ deprecation from December 11, 2017. Scheduled to be removed on February
+ 19, 2018.
+
+ January 09, 2018: Deprecated "FlutterStandardBigInteger" and its use in
+ "FlutterStandardMessageCodec" and "FlutterStandardMethodCodec". Scheduled to
+ be marked as unavailable once the deprecation has been available on the
+ flutter/flutter alpha branch for four weeks. "FlutterStandardBigInteger" was
+ needed because the Dart 1.0 int type had no size limit. With Dart 2.0, the
+ int type is a fixed-size, 64-bit signed integer. If you need to communicate
+ larger integers, use NSString encoding instead.
+
+ December 11, 2017: Deprecated "initWithFLXArchive" and
+ "initWithFLXArchiveWithScriptSnapshot" and scheculed the same to be marked as
+ unavailable on January 15, 2018. Instead, "initWithFlutterAssets" and
+ "initWithFlutterAssetsWithScriptSnapshot" should be used. The reason for this
+ change is that the FLX archive will be deprecated and replaced with a flutter
+ assets directory containing the same files as the FLX did.
+
+ November 29, 2017: Added a BREAKING CHANGES section.
